She ghosted me and changed number after making long term plans.

Why would someone do this??

Started seeing a girl. Both of us are divorced.

We hit it off, and were in constant contact. Here is where it got weird.

Supposedly her ex is playing games with their son, and won't let her see the kids unless they live together as a divorced couple. (Long story as to how he has temporary custody, but not anything bad on her part)

So she wants to live with me. Her father also just passed away and she is getting s large inheritance. She wants to buy a home with me. She talks about having kids with me.

Then all of a sudden she goes to see her son and the ex who are out of state, and she returns to text me they will work things out. Sorry.

At this point I just said "ok good luck". Two hours later she wants to see me. Misses me. Tells me she feels she is making s big mistake with her ex etc.

So now for the next couple of weeks she wants to make sure I am her bf. Great sex. Tells me her new plans etc.

Then comes Easter and he visits with the kids. She guaranteed she will never go back with him. One minute she was texting me how much she misses me, then literally ten minutes later told me to delete her number, as she is no good for me.

I call in a few days and the number is changed.

My questions.

A. Does this seem like mental illness?

B. Why would someone be almost "forcing" these long term plans on me if they are not sure? I mean she could just say lets hang it and have fun for a bit.

C. Does she miss me?

D. Will she contact me again?

E. Why leave in that manner? Not even a call? Email? Nothing.
