Need Advice - 26yo Closet Male

I have a serious crush on my friend from college. We've just broke off for summer so I'm going to miss him over the summer. I have tried to get him over for a smoke because he likes that but I gave it up years ago and only willing to do it for his company. I'm not sure about his sexuality. I'm sure I heard him say he loves me but regrettably never asked him to clarify.I just feel like I am getting to old to be beating around in the closet and if I am going to take a chance then it should be on him. He is only 20 though, enjoying life, working and hanging with friends his own age. I feel like a sad creepy old loner who stalks him. How do I/Should I make my feelings known to him?
