Lost and don’t know how to manage

I loved this guy for many years but we argue constantly! Everything is an argument. Can’t breath wrong with it being an argument. I try to stay quiet I try to reason and nothing his temper is so bad. We don’t want to be without each other but there are times I feel it’s not worth it I’m divorced and 29 no kids and I want a baby so bad but there are times I feel like I don’t want to be stuck with this man forever becuz his temper sucks but at the same time is the only person who has ever treated me with live and honesty. We aren’t even in a relationship but have lived together for the past 2 yrs and on and off for the last nine I want to let it go but at the same time I don’t. I just wish we communicated better like just calm down everything doesn’t need to be an argument but it is I figured it’s becuz we are still leaving the corks but at this point we are just friends with benefits wanting to have a future but he won’t just come out and commit either. I have no real friends I just work and go to school. I think I stay out of comfort becuz for so long he was best friend but I’m sick of the arguing and I just want to end it or change the way he talks to me! I can say it has gotten better but still I’m to the point that no matter how bad it hurts I just want to walk away but he won’t go quietly he will come back crying trying to win me back ...
