I need relationship advice please!!!!

I’ve come here because I need some help. Basically in October me (20f) and this guy (29m) started talking and we really clicked, at the time he had a girlfriend of 5 years he said they weren’t good and he wanted to end things with her to be with me I told him I don’t want to rush anything but we will see were things go. So he ended with her and we started hanging out everyday I was sleeping at his house every night we became very close and I started to really fall for him. He made me feel so loved and I just felt so happy. Fast forward to last month I noticed he was acting off and being distant with me so I brought it up and he got kinda mad and said nothing is wrong you just overthink everything I hate it. So I went quiet and just left it alone. Last weekend on Saturday he had a tournament to attend to that whole day I didn’t hear a peep from him so I texted and he was so dry with replies it just upset me more so I went to bed the next day I was so happy cause he was coming home and I couldn’t wait to see him he didn’t even want to see me so I left it and the next day I messaged him and told him something is off here you are being very distant and different towards me. He said what he always does which is you overthink everything!!!!! So I left it. That day I went to his house for the night we had sec and whatnot but then yesterday he didn’t even look at me it felt didn’t touch me once. I begged this man for a kiss and he was so annoyed like “ ugh fine” I’m like what the fuck is happening. We went to bed we always cuddle tight he slept on the far side of the bed I just went to bed crying agian and today I sent him a big message explaining everything and he ignored me. I’m just so sad and lost I don’t know what I should do and I could really use some advice !
