Confused

My 8 months BF lately has been pointing out and talking to me about what bothers him...

It all started when he decided to start using condoms again and things got awkward in the middle of having sex also in the relationship.... Today he shut me off when I was trying to get intimate before our day even started, at lunch time he told me that sometimes doesn’t like the way I kiss him and to stop been so dominant (which I’m not)... I feel like he finds the more insignificantes things about me that didn’t bother him before a big problem now... All we do is yell and argue .... I get very hurt and insecure when he tells me this kind of stuffs to the point that I don’t even feel like laying next to him .... I fell unwanted and undesired 😐
