He probably wants to make sure you are making an effort to change before becoming involved again. Seeing as you are asking this question, it seems you may need still work on it a bit.
Why would he want to hang out first? Details in comment.
my bf & I got into a fight and broke up 2 weeks ago. We havent seen each other since. He visited me at work one day but that was it. Weve been texting & trying to work things out & its been difficult but its okay. I over think a lot and start fights which is mainly the problem. Ive been working on trying to stop it and its difficult but im getting better. He just gets frustrated and doesnt like that I do it. I understand his side. He said he wants us to work out but wants to hang out before he decides. I dont understand why he wants to hang out first? Is it a good or bad thing?
Would you want to be with someone that constantly started fights over stupid stuff? It doesn't sound like he gets any peace in this relationship. What is it that you offer that he can't find somewhere else with someone that is a better fit?
He's been burned too many times with you and just wants to know you are capable of change before officially getting back together with you.
If you were wise, you would really work hard at this in order to make this work and bring peace instead of strife to a relationship.
