["I'm still kinda bummed about this, but like a month or more back I was really into this girl from Tinder and we started dating too. Unfortunately, after like 4 or 5 days, she said she wanted to stop dating and hasn't spoken to me since."]
Oh no, that really sucks. That's awful that she wanted to end things, especially since you were really into her. I am sorry.
I really got close with a girl that I met from Tinder, to the point where we were dating. Then randomly, after like 4 days, she says that she doesn't want to date anymore and then just stops talking to me.
