Overly attached boyfriend? I am getting depressed...

Hello, short stuffI am 20, male, Pole, just began studying.I meet my bf 6 months ago, 23 (ofc male), Spaniard tho, we are in a relationship for 3 months now.And this relationship is getting difficult... I can't handle this anymore.At the beginning it was OK. We were just friends. I knew he was gay even before, he didn't know about me tho. I just wanted to have a gay friend to whom I could talk. 3 months later he said that he loves me and that he wants an answer or just never talk anymore, because he didn't want to suffer so hard if it went further. I said "Ok, let's at least try."And it was a mistake. Moreover we live together but in Poland, he is just studying here.He is too sensitive... He cries over everything mental, like before the recent holidays he was crying that he doesn't want to leave me. When he is mad at me (but he says that he isn't) he just is not talking, and I am neither. I know he wants to think about that.He said that I am the good one and he the bad one in this relationship, because I got lots of patience and he doesn't. Yea... He screams at instant over most of the things that I do (by mistake), like pouring some water out of a cup for tea, or last time before he was leaving to Spain he gave me his sheets of papers so fast that I couldn't hold all of them, it was in airport, and he started screaming at me in front of all the people there... I didn't say anything. Later he apologized and said that he is just scared when it comes to flights. But often after any argument he cries that he shouldn't even begin...During these 3 months I have noticed that we are arguing over such pitty things like "who should throw away the garbage" or "who should clean this week". It can turn into such a big one argument...Even tho, he is too attached to me. FFS... It is just 3 months and he acts like we are in a marriage... He is even talking that we should adopt some kids in the future, and when I reply "no, don't think about that" then he says "why? you won't love me anymore?" and I am like "what to say?" - YEA, I BEGAN TO STOP LOVING HIM... I don't know if I love him anymore now. It was cool at the beginning and soft, now it is tough and difficult to even breath when we are after an argument.Now I am at my hometown and he is already in Poland, at our flat. I am not able to drive there (with my car) because I am really ill and the roads are slippery. I had to be there 4 days ago. Now he is saying on messenger (facebook) that something is not alright. Now I feel angry but before we had quite a good conversation during the whole holidays. I was actually getting openly-minded and I was even answering often than when we were talking before getting into a relationship. But he said that I am not answering often and right after him. AND THAT I DEFINITELY STOPPED FEELING SOMETHING. He said "I don't know what the problem is but I hope we will get through this, because I want to be with you forever". Is it even possible to say such things after just 3 months? He says also that I am the one man that he will ever love the most in his life. That I am the 'one'. I don't feel that towards him. I even asked him if he can take this relationship easy, but he replied "What for? Aren't we made for eachother?"Now the most important thing: I am 20, but I discovered that I prefer men over women 1-2 years ago. I come from a small town, here even the adolescence goes slowly. Moreover, I know nothing about relationships... Before discovering that I am gay I thought that I am just asexual. So I didn't even have any interest in 'love stuff'.Now I am getting depressed, because while talking with my bf it's like going through a maze. And the plants are hitting me at every step I am taking...I ask just only for some opinions or what should I do... I don't know if I am the problem or him, or something else.
