Questions: Break Up & Divorce

I started “seeing” this girl a couple months ago and it took a while but we started to hang out and have lots of sex. Talked about things that are more serious such as our past and what we’d possibly like for our futures individually or together. But I always saw in her that she was not very serious in actually getting to know me or be with me. She just had fun with me and pushed away anything that was below the surface, mostly. Then after a while of having sex, and meeting at our places and having few dates to bars or restaurants - she voiced her loss of interest in different ways and it hurt me and made me feel less than and at fault for being too serious or not enough, etc. So then I tried for about a week or maybe a bit more here and there to talk to her and make changes and scale back so that we can still see each other and have sex without expectations (basically I was willing to settle and sell myself short of what I really wanted/needed to feel good with someone). She still pushed me back and said we should split ways. I let her go. She then added me back on snap me a week later and tested all kind of stuff relating to having sex and how she misses me and wants me inside her and cuddle her, even started saying that she’s in love with me and asking me if I am in love with her. Etc. then I called her and found out that she was drunk and a little high. She was out of town for family Christmas. She told me that few weeks from now she wants to see me when she comes back. The next day was Christmas Eve and I called to wish her merry Christmas and all that. No answer. So I went no contact. A month goes by but she was still on my snap. Watching my stories. But she would never post none or had me restricted from seeing it. Then she started posting pics and I saw one where she was back out of town with some guys. No idea who they are. I still didn’t contact and stopped watching her stories. Then she deleted me after posting few more pics and I didn’t watch her story.
