Background: I met her at a club thru a mutual friend (not really close). I slept over the first night. Didnt have sex but got to third base. Had dinner with her a few days after that and f-closed (dont like that term but whatever). I asked her to be my gf but she said we just met, lets get to know each other first.
We went out to movie once. We had dinner a couple of times and I paid for everything (she didnt try to split the bill or anything). I made sure dinner wasn't super expensive tho (so doesn't look like I was trying to buy her dinners).
Anyway I went to NY/Miami for spring break and after that it kind of died...

Over spring break, our mutual friend texted me...
him: I heard you were in Miami? Ultra?
me: Nah just chilling on the beach
me: U celebrating [name]s bday?
him: Yuppp
me: Haha nice make sure she doesnt go too crazy
him: She's not
(red flag right here)
me: What r u guys up to?
I already sense a red flag from talking to our mutual friend. This was around 3/29-3/30
Another background info: I made out with the mutual friend's ex. And I also made out with another friend of his one time.
The mutual friend probably killed my relationship with the girl. Not sure if I did anything badly over text... I tried to not sound needly over text, but I guess I did? I was wondering if there was anything I can do to save it.
