I can understand where you're coming from, I think one of the hardest things to accept/deal with when breaking up with someone is knowing that I'll be totally insignificant to them, especially when they get into another relationship. I did get over them though, it took some time but I moved on. But yeah, it's weird to think about how men I once cared very deeply for don't give two shits about me now, it still kinda hurts, although to be fair, I don't really care about them anymore either.
