So I was talking to a girl on bumble for a few days pretty much all day. Graduated into voice messaging and honestly I’m pretty socially aware and it seemed like it was going very well. Better than any other girl I’ve matched with on the app and I’ve gone on dates/hooked up with a few people on this app (we’re all still friends it just wasn’t meant to be) So she’s in school for medicine and she has an end of semester project due today (Sunday) yesterday I sent her a message she replied an hour later saying she was working on her project just an update and she’s enjoying the hell out of talking to me but she has to lock in for her project so she’s avoiding her phone she’ll get back to me soon. I respond “yeah no problem do your thing I don’t use bumble that much and don’t know their “rules” when it comes to the time limit here’s my number in case. ###-###-####” night goes by she doesn’t message. This afternoon she’s still in matched. I just checked in and now she’s a deleted user. I’m 35, like….what did I do wrong she and I seemed to have a solid connection. Ladies is it really that big of an ick to even just give you my number? She could have easily just replied in the app eventually and said I’d rather keep it on bumble no? Idk I just feel like dating is cooked if I could have that good of an interaction over several days only to be ghosted like that granted I didn’t get unmatched I can still see out convo but still….
