Need some advice please

I’ve been with my bf for 3 years now.....we were suppose to move in together a month ago once he get a house but I didn’t. He never ask me to move with him, I helped him move that day and all day long he just ignored me. Ever since he has been very distant to me, I don’t see him if I don’t go to his house, we don’t have sex unless I go see him which is like once a week (from having sex three to four times a week) less calls and texts....so I gave him his space. Now I feel like I just wanna be single and alone, I don’t feel the love from him anymore, when we have sex he does it so hard like he is trying to punish me or releasing all his anger in me. Now I hate having sex and I just want to be alone. I love him with all my heart but I just don’t know how to leave a situation like this. I talked to him about it he said he is just stressed that’s why he changed......
