What is the best thing I can do to get my ex boyfriend back?

My boyfriend and I were dating for a year and a half. We split up a little over two weeks ago due to many differences and lots of on going unnecessary fights. I don’t feel good about this at all, we were so in love and talked many times about having a family and spending our lives together. I never thought he would want this to end, even with all the fighting, I always thought we would work things out. About a month ago we got an apartment, which has made this break up even harder. I realize there has been a lot of stress on his part, working two jobs and so many things he would like to get done, but as a couple (in love), don’t you work together and not give up regardless? The last fight we had which was, well the day of our break up, he said that he just hit his breaking point and that things would no longer work for us, we’re two different people. I just don’t get it, why after we just take the step of getting our own place is he so sure that we’re not meant to be? After all that we’ve been through together? I know that this man is sensitive, emotional, and caring, but all ive seen these last two weeks is someone who acts so careless towards me, like he never even loved me. Is that just a front? I want him back so bad! He says there is no chance, but isn’t it too soon for him to even tell, I mean in time will he realize that maybe he made a mistake? If he ever truly loved me wouldn’t he want to work something out eventually? I know I was frustrating him with all my meltdowns the first couple weeks, but i’ve decided to take a different approach in hopes to win him back. I’m going to work towards my independence, not harass him, give him his much needed space. Anything else I can do to make him realize that he should give this another shot? Please help, this man is impossible to read! Every response I get is emotionless, and I just don’t see how he can be ready to just forget about me after a year and a half. Just want to add there isn’t another girl involved in case that’s what you’re thinking, I know that for a fact. He just said he can’t live with the stress of things anymore. But I know that if he would give me one more shot, I would do my absolute best to keep him happy and avoid the fights at all cost!!! Another detail I will add is that even though we have an apartment, I am not staying their through the night, I only come and go if he is not there and at work because I have no place to take my things to at the time being. We also work together so it is probably more difficult for him to even have opportunity to miss me and really think about me being completely out of his life. Right now, I finally stopped having my meltdowns in front of him, i’m trying to show him that I can act like an adult and keep it together with confidence so that we can still be friends. I’m trying to be that girl that he was originally attracted to in the first place. Please help me.

All you can do for now is be a friend.. Be that person you were at the beginning.. When at work try not to be around him that might make him miss you.. You can also just be there simply if he needs you.. Try being the one where he can go to if he needs to but don’t be persistent in your attempts to get him back.. Act nonchalant around him and maybe he will re-think everything.. Best of luck.. I know this is hard.. Best of luck..
