Please help me

My boyfriend and I have been having issues in our relationship for the past year over sex. He can go weeks without it and it hurts me I feel this huge disconnect and I want to have sex with him . Well this last time it's been a month and a half and I expressed my feeling n told him how it was making me feel it was a huge argument and finally last night he lays next to me naked pits my hand on his dick and is just waiting for me to suck it so I do but he does nothing for me doesn't even kiss me he tells get ontop and it wouldn't even go in because I was so dry and when it finally did he didn't kiss me I tried to kiss his neck he moved away he busted and he didn't even care if it felt good for me and I went in the bathroom and cried because I just know our relationship needs to be done . How do I let him know I love him but I can't do this anymore and he needs to move out
