<human>: Can you succinctly summarize the text in 1-3 sentences?

Im at a standstill in my relationship.  We have been fighting a lot lately. Basically,  he has issues with interrupting and talkimg over me. He has had the issue from day 1. He used to try to fight it, for a few months everything was good because he actively watched his interrupting and made sure he did it less. Now he has stopped trying. Conversations are hard,  especially when I am upset. He regularly interrupts my sentences and puts words in my mouth (eg. I told him he should be nicer to the people at his work, he interrupts and says "so you're sticking up for X Person?" & im like,  "No, I was going to say be nice because you work a lot of hours wi th these people in a small place. Be nice to them to make your work life easier.") It creates many miscommunications between us. Now,  when I bring up the issue, he likes to tell me, "Well I may interrupt, but you do xyz," & I say ok, I can work on that,  but how can I if u dont take the interrupting seriously?" Another new habit he has is not apologizing. This happens often.  He told me today I needed to see a therapist from before we started dating (I am fine, he just stresses me out) & I told him I took that offensively and I asked for an apology.  He said he wasnt going to because it 1. Was true and 2. Was a "statement" not an "insult" (???) Basically he is no longer the man I fell in love with and when I told him that he told me that makes him feel mentally abused (????) Does this guy even care about me? He says he loves and respects me but im so confused.  Is this even worth working out? Every time I bring up an issue its because of me. He isn't to blame for any problems, he turns everything back on me..
<bot>: bf is not very nice anymore, respectful,  or kind.  Doesnt apologize for anything.  Blames me for everything.  Then says ill never find another guy like him again.
