Tldr texts me "happy new year ๐Ÿ˜˜๐ŸŒนโค" after I blocked on social media and deleted number. Want to text "who's this" but feeling I should just ghost. What do I do?

Ill try to keep this short and sweet.

Basically we are off and on and she kept saying she's gonna stop talking to me kinda jokingly but I guess I'm too hot for her to let go (I'm not that great but I guess I am to her) she almost never denies sex if I initiate and kiss her cause she "can't say no"

Well on Friday or thursday we had dinner and she told me that she planned to go to a party with Co workers on Saturday and then leave the party at 2 am with a male Co worker. His mother would drive them both back to his place...

Then on Sunday she would be getting her nipples pierced with a different male coworker. (Their gay status is questionable to her but she thinks one is bi...the other might be gay. Given her job I'm inclined to believe this but I still have my doubts)

When I reacted (dumb I know) she said "you never asked me if I had plans" in a joking way.

She wants to settle down but I have a hard time getting close to people so maybe she just trying to get me to commit?

I do miss her sex, cuddling, etc. But she can be either stupid or flaky sometimes...

What do???
