Would it be weird to contact my ex, whom I haven’t talked to in a while? I regret the way things ended between us, and I would like to sort of mend things. I’m not looking to get back together, because she’s away for college, but I feel something is better than nothing.
Before we dated we were best friends. Then it sort of fell apart. So, really, what I’m asking is, would trying to contact her to fix things by a good idea? And if so, how would I go about it?

We can’t answer that without more information on why you broke up, so I would say no.
I know how you feel. I got my heart broken and then he asked me out again, so I figured sure a second chance then I just got broken again. It kind of depends on how everything ended and who broke the relationship off, but if it happened to be you that broke it off then try to apologize and then see if you can repair that broken friendship. If it was the other person maybe suggest the repair, but let them make the first nail being put in official.
