Confused

So I ended my 3 year relationship because he was always “too busy” with his friends or hustling and “couldn’t answer”. Mind you that we always talked or were together at first but at the end it seemed like he didn’t care. I get that he wanted to be with his guys but I was always at home because he pulled me from my friends (which I was okay with at first). Now 1 month and a half later he “realized what he had” and wants to be together because he “loves me”. I don’t know what to do!!!! I know things will change for awhile but we’ll be back to the same place. Should I just ignore him? Should I give him another chance? We had a great time together and I considered him my best friend even though he would say mean things if I was busy at home or at college, especially with group projects.
