I messaged an ex and honestly I don't know what to say really... It's been a few months and figured I didn't have anything to lose at this point obviously. I texted saying I hope she's been doing okay, she didn't even recognize the number, so I told her who I was then she just said hey and that she's been doing good, but didn't even ask anything in return... I guess the fact that she responded is good. Any tips for me?
