is my boyfriend losing interest

me (21) and my boyfriend (23) have been together for 2 years. for the past few months he has been slowly being less intimate with me. nothing else in our relationship has changed, but it’s gotten to the point when i even try to kiss him he accuses me of trying to get him “turned on” and he “isn’t in the mood right now” but it’s been months of him not being in the mood. he used to initiate intimacy every. single. day. oh and there have been times he’s physically pushed me to the ground or off the bed when i’ve tried to make any sort of move. he’s way bigger than me and those times have been pretty scary. physical touch is definitely a big part of my love language and for the past 2 years (up until now) it’s been his too. i wouldn’t even care so much about the not having sex part if he would still hug and kiss me regularly. it’s getting old. i’ve tried to talk to him about it but he shuts me down. nothing crazy has happened in his life that would make this make sense. has anyone dealt with this before ? do you have any tips on how to get through this or what i could do ??
