This guy is really confusing and did I handle this right 🤔

You know it’s really hard to be in control of your relationship and communicating with a guy when he’s throwing you mixed signals. The common mistake that I made in this so-called relationship or I liked to call waste of time ship was give this guy too much effort without getting effort in return or just enough to keep me hooked on him. I’m in college and I work in a dorm hall helping residents. This all started last semester Fall 2017 and I noticed this guy (I’ll call him Mark. Not his real name!) while working at the front desk he always walked by to go to class or to go to the clubs he was in and I thought he was cute, dressed pretty nice and seemed like my type of guy. The only problem was I thought he was straight by the way he carried himself and my gaydar is trash!! While on the job and throughout the rest of the month I would constantly see him staring at the desk while he walked out of the main entrance and I really didn’t think anything of it because of course I thought he was straight and I don’t entertain straight guys thank you. But I eventually developed a tiny crush on him.I would constantly see him places on campus or around campus like at Whataburger near campus and the football games and he would constantly stare at me and I’m really dense so I just thought there was something about me that he was curious about like most people stare at me because they like what I’m wearing or they’re just staring and never thought he would be interested in guys. And his best friend being around him all the time gave me the impression that she was his girlfriend.I finally got the nerve to talk to him while working my shift on a Sunday around 3 weeks before finals and he walked by the front desk to do laundry, I stopped him because one, I wanted to talk to him and two, I wanted to ask him what race he was because I thought he was something different from what he actually was. He laughed and told me what race he was and by talking to him I could tell he was not straight he asked me my name, and I asked for his which I established that his name is “Mark.” We had little conversation and he left. Through the week I would see Mark and his best friend let’s call her Shady because she always had a look like she knew something that I didn’t, so we would greet each other and continued to have small talk. Eventually on the next Sunday he did his laundry as usual and he asked from my snapchat and I gave it to him and we friended each other. The same day I invited him to the rec after my shift and he accepted. During our workout/hangout there were no awkward silences or any red flags at the moment and I was really feeling his guy. So afterwards we showered and went to eat at the dorm cafeteria and he invited Shady and I was like okay, so he is seeing if his best friend would like me, two can play at that game, so I texted my best friend the situation and she arrived at the cafeteria faster than you can say hurry up. He seemed very invested in me and paid no attention to our best friends while we would eating dinner and my best friend confirmed that he was interested in me.Red Flag #1: We started snap chatting and developed a streak and eventually he started leaving me on read a lot even though the conversation wasn’t finished. I never double messaged him after he left me on read and he would constantly message me with something random after I didn’t snap him back after being left on read and the boy was terrible a responding like 5 hours before a response. Our streak continued and I overlooked it of course.Red Flag #2: I went to his room for the first time and I had to ask him for example he would ask what am I doing and I would say studying and he would be that person who wants you to ask the obvious question so I said “you want me to come to your room?” He said yes, so of course I left where I was studying and went to his him room. We got to know each other more and didn’t really get a chance to do anything contact wise because of his roommate and same goes for my room and THE BOY NEVER REALLY WANTED TO ADVENTURE OUT OF HIS ROOM. He always made excuses where he couldn’t go outside of his room and when we went to eat at the cafeteria together Shady would be there as well so never really eating alone.Red flag #3: It was the end of the semester and he wasn’t from the college town and I asked him if he wanted to hangout after his last final before he left he declined of course which was annoying and he left and went back home. He would still snap me and we would go back and fourth with our conversations and I asked him where he wanted to go with this he said he wanted to take things slow and I was like okay.Second semester started and we hung out in his room and that was the last time I went to his room and I finally got fed up with his shit and ended the streak after 45 days and all he cared about was the streak it seemed.He still messaged me after the streak to see if I would respond and I ghosted him and come to find out I told my co worker the situation because he was like my gay godfather and he said that his friend went through the same thing with the boy and I was really?! And it gets crazier, my co worker talked to Mark and Mark admitted to leading guys on and then stopped talking to them because of his past relationship and I was really confused on why a person had the nerve to do this but I ruined his streak because I ghosted him first. 💁🏾‍♂️After this he still talks to me and is friendly and since I’m very friendly person I’m the same back and I finally deleted him off of my snap and he still looking at my stories and he still stares at me I really don’t know what to think of this because the boy is really confusing and I don’t know what he thinks of me. He recently stopped coming up to the desk to talk to me when I’m working because I guess he got the hint but he still stares at me and smiles when we make eye contact. He’s also on my mind a lot and he shouldn’t be. And he seems like he still interested in me. What should I do?
