Feeling lost and exhausted from trying

Where to begin? I have been with my boyfriend (M25) for just over 6 years now. All was great in the beginning. He was everything I ever wanted. Absolutly perfect in my eyes. 4 years into the relationship and I caught him emotionally cheating on me. With a girl I introduced to him. We were broken up for about 3.5 months and he continued to see this girl and I dated as well. The one day i had decided to unblock his email he requested we meet for dinner. I agreed, and the entire time he could not stop crying. And thus he lured me back in. Cut to 2 years later, our current situation. I am 24, he is 25, both have stable jobs. I have mentioned moving in together but he disagrees and his feelings will not budge at all. He also refuses to give me a key to his apartment. I have since given up on that idea. However, for the last year he has stopped inviting me to his family get together (I have never had an issue with his family whatsoever, and his mother even asked me why I would take him back), he also doesn't invite me out when he goes out with his friends, and I always find out later that his friends have invited their girlfriends and their friends. He was never a big drinker at all, and after deciding to live a much healthier life i decided to quit drinking, half of that decision was for me and, admittedly, the other half was to find something to re-connect with him. I have resorted to begging him to come to the gym with me so that we can at least have one activity to do together but he refuses. He hasn't shown much interest in my knew healthy lifestyle. In fact, He doesn't know the name of the company Ive worked at for over a year, and if I showed up with a green Mohawk he would not notice. He plays football and I am constantly trying to make plans with him around his foot ball schedule. I basically act as his personal assistant when he makes plans and forgets certain dates. He doesn't appreciate this either. But when i try to make plans with him he will wait to hear if something better comes up with his friends and will completely blow me off. He doesn't see an issue with this. I don't feel appreciated or loved for that matter. We have been fighting non stop and he has problems communicating with me. We are both stubborn and im definitely not perfect whatsoever. But i find i am the only one who ever tries to fix anything. I'm constantly apologizing for getting upset and he always has the upper hand. He is selfish and manipulative. But I cant seem to leave him. 6 years is a long time and we haven't taken any further steps. These are just a few problems Ive mentioned to him in discussions but I'm feeling lost at the moment since he doesn't communicate and claims im being psychotic. Any kind of advice will be greatly appreciated. Thank you so much!

You are mad at him, he dominates the relationship and have outgrown him. I think you need a new man. Break up for a few months and both can either end it or start over again. As it is the relationship is not making either of you happy.
