Well I do believe that people can change, but I think you have to be completely over and trusting of him now.
I don't think I can date my ex again because I KNOW they haven't changed and I would never forget what they did to me.
But its all about the mindset. If you go into it positively, then things are more likely to end that way, but that doesn't mean that the same bumps you encountered before won't be there again! Hope this was helpful.
I never have. Of course by the time me and my ex's broke up we wanted to practically kill each other (except for a few where we simply agreed to call it quits out of boredom or whatever before it got to that point) so tend to never even talk to each other again after the initial breakup.
They don't really work. And if you broke up over something dumb that to me says either you never really cared which is why something dumb got in the way, or you guys weren't really mature enough for the relationship.
But i think you'd be better off staying away, but go for it if you want.
