I NEED SERIOUS RELATIONSHIP HELP!

Okay so me and my bf have been together for about 1 year and 7 months ..Everything in our relation was Gucci until about 3 months ago where He basically stopped saying “I love you” ...This is a really big thing in our relationship and he just randomly stopped! He’s been acting very very off with me on text just basically giving me dead replies and he’s stopped coming to see me like I see him like once after 3/4 months. He doesn’t say he loves me but then he came over to my house after 4 months and before he left he said “you’re not allowed to think I don’t love you and don’t care about you”.As soon as he got home he started acting dead with me again? I’m so confused because I tried to break up with him and he’s refusing to let me go as I’m his first ‘love’. Also during our relationship we were very sexually active but he’s never ever made me cum like I make him cum all the time but I’m too scared to actually tell him ( I’m sorry it’s a lot to take in ......I know)

I NEED HELP!!!!!!
