Where do I go from here?

[NewB3]

SO I have made it top priority to be free. I have a new friend. No relationship interest, just having fun together. WAS started some strange things this past week while I had S11 and S4 for spring break. I sent WAS one picture mid week of both kids. I shared a second text moments later of something funny from the trip. She replied LOL. I gave her some funny story in the followup and said S11 would send her a pic of us. (all 3 of us )
This past week, my WAS took my oldest son from a previous marriage to breakfast. She invited him Thursday night for Saturday AM. Upon returning, hung out for a few. I offered to let her sit down, she said she needed to use the restroom. (first time ever doing that here) She came back and sat for about 10 minutes chatting with both kids. At pickup on Easter, she came over and sat on the couch and chatted. S4 saw a pic on my phone from our fun week and scrolled. She sat and scrolled with him asking questions about the pics. She stayed almost 30 minutes. Comments about how nice the house looks or something that I have changed is noted and complimented. She held S4 on the way out and half way to the door said, give daddy a hug. She leaned back towards me for that. I put my hand on her shoulder and gripped him for a hug. Kissed his cheek and said I love you. I did not put a name on the i love you. Let her think what she wants.

Today would have been our anniversary. I would and have not called her for any reason other than a quick call about kids. Rarely. She usually reaches out. Today she called me on my way home. She asked questions about S4 and reminded me she needed a paper for his school and a special toy for school. Said she could come get it thursday. I told her I had plans and Wednesday would be better. Found out that her normal Tuesday Therapy appointment was no longer. Said she had not been in a while.

I have done well dropping the rope and moving on....then this happens. I feel like I have back slid tonight. I cannot help but wonder WHY. Why call, why the sudden changes. I am not chasing, overly accommodating, needy, nor do I touch her or reach out. Although I have grabbed her hand on accident when handing off stuff. I invited her to NONE of the easter festivities I took the boys to. I felt she would feel that was needy of me and I do not want to have her feel I am available.

What could she be feeling/thinking? No therapist, no people in her life other than parents, child, and her work from home. She is getting her alone/personal time. Until she reaches out to talk, which my therapist said will come, I am moving forward with my life. I cannot just float here waiting for her.

Thoughts? Advice? Been a while since I came here, but I needed you guys again.....
