She came back then went

I’m having a hard time understanding my situationship. Me (28M) and this girl (29F) from my past have been seeing eachother since end of December. She swiped up on my IG story, I invited her over, we talk about dating intentions, she said since she’s still in school she doesn’t want to worry about a relationship. At the time I was cool with it.

Fast forward to the end of March, things are hot, lots of raw sex, sleep overs, dates etc almost every weekend or every other weekend.

Even towards the end of March we hung out like 3 weekends in a row. Then all of a sudden next week in April I ask her out again and she goes “I need to prioritize my assignments” that’s when she got distant. So I gave her space, didn’t call her until 2 weeks later in mid April. Not much communication from her during those times but I ask her to hang out and she says not this weekend but the next. So end of that month she comes over, sex, sleep over, cuddling until 1pm the next day.

Up until a week later it was radio silence from her, she calls me on a Monday, I tell her let’s hang out then we plan on a Saturday beginning of May. She flakes and says “can’t do today, celebrating mom’s day”. I just ended up ghosting her message and didn’t talk to her for 3 weeks. She was liking my stories though so I decided to call her. That’s when last weekend she came over, sex, sleep over, cuddling naked. “I missed you so much” “this ___ is yours”

That was a whole week ago - since then it’s been radio silence once again.

*context* this girl seems jaded from her past, she goes to therapy, she tells me “men are liars” etc. has that I don’t need a man mentality.

I never told her I had feelings for her since she always kept me at an arms length when she got distant.

I’m just confused, she flaked on me, I ghosted her, and called her up and she came back?

I’m sure there’s maybe another guy in the picture? Did she just miss having sex w me?

I’m planning on never calling her again

I’m trying to understand. If anybody can give me insight on a situation you had like this or any advice. Please let me know!
