Relationship problems

Throwaway for reasons. I'm turning to r/gay because I trust this community and I feel like I fit in. So I've been with my boyfriend for 3 months or so (he'll probably be reading this so hi). I am not sure what's going on with me at the moment, but I'm young and I don't really like myself. I met him and I felt like, for the first time, I really fell in love. Last week I was at his house for the day, which is a big deal because he lives 2 hours away. Long story short he makes me feel special and happy and I like feeling like I'm working h something. I've noticed though that since then he's been acting more and more oddly towards me. Whilst before he would text me twice a day and we'd talk about anything, he's stopped initiating conversation at all any more and always seems to have an excuse as to why he can't talk to me. It's beginning to wear on me and I feel depressed, which is unusual for me and I really don't like it. I messaged him last night saying it felt like conversation was forced and that if he wanted to tell me anything he could, and he admitted that it felt like it was a lot of work to talk to me. I get that, I'm pretty sure I'm clingy. Couple that with the fact that I'm ugly and don't like myself, and that he's incredible, and I can't help but feel like he's putting any feelings of affection on for me. I want to stay with him and at the moment I only really feel happy when I'm talking to him, but at the same time I don't want to be living a lie. What do you recommend I do?Sorry for the wall of text, I just kinda got typing and didn't stop.If you're reading this, message me. I don't want us to end.
