I really need advice😣

My boyfriend and I have been together for almost two years now and lately we have been having a lot of fights and issues. We have had discussions on how to better our relationship and make it work but it seems like even though I tell him the things that pisses me off and I don’t like he keeps doing them and what he told me that he doesn’t like is that I’m always angry at him and I’m not as happy/fun as I used to be. The things that I don’t like include always saying dumb things like “Oh it looks like you’re too busy talking to the other guy so I’ll just stop bothering you” or things similar to me talking to other guys when I don’t. I only talk to my mom and him and he knows this. Also another problem I have is that he always grabs and touches me in inappropriate places while we are out in public. I always tell him to stop and that I don’t like when he does that but it seems that after I tell him this he keeps doing it more on purpose. Also, every single time we see each other we have relationships and honestly, even though I like doing that, it is getting tiring because it’s becoming a routine and that’s the only thing we do when we see each other. If I invite him to the park or to the store he never wants to go and always says “why don’t you come to my house instead”. Today we were having a discussion and I was telling him all of this and all he kept saying was that if you don’t like me the way I am then Just tell me and we’ll leave it at that. He would also tell me that why don’t I just find someone gay who won’t touch me or have relationships with me and that he was gonna look for someone who lets him touch her body and won’t care where and has relationships with him everyday. I’m pissed off at him for all of what he is saying and now it’s like I don’t even know him. He used to be very sweet and respectful to me, now... I don’t know what has gotten into him or if he’s really this way and has just been hiding it from me. I really do love him and I know he does too but I have tried all I could think of to better our relationship but now it just seems like he’s given up or doesn’t care anymore. I don’t know what to do anymore..😞😪 Can any one give me advice on how to deal with him and better our relationship? Or any opinions on him and his behavior?
