I need advise. I don’t know what to do anymore.

Lately I’ve been feeling completely insecure and unwanted in my relationship. I’ve attempted to sit down and have a conversation with my partner, but he always seems to think I’m attacking him.. Sex isn’t enjoyable for me, I don’t get made to feel sexy or wanted, it’s like “come on let’s get this over with”. We have been ttc for a year and a half now, but I’m starting to realize my dreams of being a mom may never come true with this person, and I’m having a hard time. This is someone I want forever with, but I can only take so much. I need help on what to do next. I feel completely helpless. This is my first serious relationship and we’ve been together going on 3 years. It was never like this in the beginning but it’s gotten bad, I get called names almost everyday and he never fails to remind me how annoying and lazy I am. Are we done? Did we have our run? Or is there a chance to heal?
