I need help understanding this

Okay so about two months ago I started talking to this libra guy, we have only hung out twice due to his busy schedule and also mine as well. Both times we hungout we were at my house and we cuddled and watched netflix, the first time we kissed and that was it, but the second time we made out, no clothes came off but still. When we first met we both agreed right off the bat we didn’t want to just jump into having sex that there is so much more to it.

Well things were going well, I called him my boyfriend to him directly and he never corrected me, a friend of mine called me his girlfriend directly to him and he never corrected her.I called our hangouts dates and he never corrected me so a few weeks passed and he started going cold and being distant, so I had my friend message him to see if he would talk to me and she did and he opened her message and replied to me and unadded her from snapchat, because that is how Libra and I talk is through snapchat. He went from calling me beautiful, and sexy just about every single day to barely talking to me and now its at the point he is opening my stuff and not replying, I have only sent three snaps back to back that he has opened and not replied too, used to he never left me on read, I know he has finals at college this week but I do not know what is going on, because he was literally hung on me and now it’s cold and nothing.

Last week when things started fizzling out i asked him how he would feel if we made things official for christmas, and I fucked up because I didn’t clarify what I meant, which was for nothing to change except for it to be facebook official. He replied with “Sorry I really am but I don’t have time to be dating right now.” After that he barely talks to me, saturday it seemed like things were back to being okay, because I told him I wanted to continue how we are with him and then sunday he opened everything and ignored me so I sent him a good luck with finals snap and he opened it today and hasn’t replied at all.

I am not sure why it would piss him off but when it all started fizzling out he said “I want to see your beautiful sexy self stripped” I replied with “and you will for my birthday if not sooner. It may be my birthday but you’re in for the surprises.” Then I sent him one that said “I wish you were here to cuddle me and make me feel better.” and he replied with a “yeah” so thats when I knew something was up, and this happened before I asked him to become official.

I don’t know what happened. I used to send him sexy snaps and the goodluck one was a sexy snap too but he didnt acknowledge the last few I sent so that is also when I knew something was up because he always either screenshots them, or saves them to his phone or he will acknowledge them and say something.

We are two years and some months in age difference, him being older. He works and goes to college full time.

He really is a great guy, and I have fallen deeply for him, and I want to know if this is one of those things where he needs space to re balance himself or what is up, because he seemed to be wrapped around my finger until last monday, even my friends agreed that he seemed to be starting to fall for me as well. I don’t know if maybe he has something family related going on or what because he is so closed off about it, he has opened up some but not much. everything is so different with him, and I seriously do not want to lose him, I want to go back to being his unofficial girlfriend which is what I was and still am in my head and hopefully his since he seems to want to continue as well because I asked him if we could and he asked if I wanted too and I said yes, so.

We even had made plans for future stuff as well. This seems so unlike him, one last thing he always takes forever to reply, between an hour or two and it has always been like that, but he never left me on read except for one time and he forgot to reply but that was when we were good, now he takes forever to open them and when he does he doesn’t reply. As described above, I haven’t gone crazy blowing his phone up either, because I am trying to give him space if that is what he needs but someone please help me. I don’t understand how he went from calling me beautiful and sexy in the same sentence and then overnight everything changed.

I should also add that both times we hungout not only did he actually kiss me but as I just laid there cuddled up beside him with my head on his chest he kissed me on the forehead and the top of my head multiple times, too many to count.

Quit messaging him! If he isn’t replying, don’t message him. I think you jumped the gun... he never asked you to be his girlfriend and it doesn’t sound like he ever even took you out on an actual date?
