For context, me and my boyfriend fight a lot. Every week there's some debate going on, which I think partially happens due to my mental health, how anxiously attached I get, and other personal issues of mine.
We've been together for about 3 years and we've gotten to the point where we're **seemingly** comfortable being completely honest in how our behavior makes the other feel. I actively try to encourage clear communication, and for a while I thought he agreed. But since around late March, he's sugarcoated how things make him feel, and begun writing off my feelings he used to swear were valid as non issues or overdramatic, then turns around and says "we're hormonal teenagers it's fine and normal to act how you do."
He's always compulsive lied since we were way younger so I've had issues with trusting him and it doesn't get any better the more he demeans how I feel/takes no actual accountability for his words beyond "I'm sorry I made you upset." I know we're both very lonely outside of eachother and we're still very immature, but I just feel so stuck because he keeps insisting he will never change. Straight up he'll tell me certain traits of his are unmoving and I'll just have to deal with it.
What should I do? I've already communicated all I've said here and it's gone pretty unacknowledged.
