you broke up with her for a reason, right? would the past problems still be there if you got back together? i'm thinking it's got something to do with one/ both of you being insecure as you've already said? it's all good and well to be happy when you're together but it's when you're apart that you see the strength between 2 people and it seems that this isn't holding out. i think you're right about the heart break and it's already caused a lot of unneeded drama. you may also be in for an opening up of old wounds. is all of this worth a POSSIBILITY of something MAYBE happening? that's up to you but i don't think it is.
They called us a dead generation,
They told us that we wouldn't survive
They left us alone in the maelstrom
As you can see we're all clearly alive.
