Most Helpful Guy
Well for the record, I have never heard of a couple that broke up and then got back together and ended up working out. He dumped you so if you got back together, it might be nice at first but then the same feelings that made him break up with you in the first place would come back and he would break your heart again.
When he says stuff like "just forget he texted me and that he shouldn't be bothering me" it sounds like he's trying to manipulate you, so don't fall for it. It's been 6 months so hopefully you've moved on and you definitely don't need to talk to him.
