Divorced and moving out.....still hopeful

[NewB3]

This has been a week of very interesting interactions. What do you make of this?

I was off all week with S11. Talked to ex and said since s3.5 has a birthday soon, I would like to take cake and such to his school. She said the teacher and her had talked about later in Jan.. However, she would check. Well, it worked out. She was happy that I was doing that and s3.5 was prepared for my Monday visit to drop off the goods. He had a great day. I had also asked her about visiting on Christmas morning. She said she would not be able to hold him back to wait for my arrival once he awoke. I let that slide. I then mentioned having s3.5 during the day Tuesday and Wednesday she mentioned I could also keep him Tuesday night to spend more time with both kids. So we did. We had a great time. I emailed her prior to Christmas Eve and said that I lived less than 10 min. Away and would be glad to be ready for a call when he awoke, or could come sit out front in the car until called. I said" if you would rather not have me there, please just say so. Well, that got a call. She said I was more than welcome to come. Strange contrast to the comments on the first asking.
I dropped them off to each ex on Christmas Eve. She had gotten a large piece of furniture delivered and was unboxing. I assisted and she was appreciative. I did however, leave her to move and assemble.
Christmas Day I was there first thing. Her parents arrived also, with breakfast. We went in and exchanged gifts. Yes, she got nothing for me. I had three gifts for her. On from the boys and two from Santa. Nothing over $20 each, but very unique and thoughtful items. I had something for the dog, and both parents. Parents got a gift for me, as did s3.5. Ex got a splinter. Was working on it and made a big deal if it. Not like her... She went to get tweezers and the came to the room asking her mother to take a look. No glasses, her mother said....ex handed me the tweezers. I handled it and continued talking with s3.5. I hung around about an hour and then as parents were packing up breakfast, I grabbed my coat and wished everyone a merry Christmas and thanked her for having me. She said " oh your leaving already"? I said yes and made my exit. Told her I would be back at 3 to get son. She said she would bring him to my home.
Came home and prepared house for s11 & s3.5 visit later that day. Then went to my family lunch. She called at 12:30, left a voicemail asking when I thought I would be home. I called her about 1:15 and said I would be there by 3. I told her I would text when I got close. I was 2 blocks from my home and pass her on the road. S11 & I get home, unpack gifts and she arrives about 2 minutes in. Chatty and telling me what they had been doing all day while her parents were visiting out of town. ( our divorce and schedule kept her from going.)
She comes in and walks him to the tree and stacks of gifts. Asks if she can watch him open. ( I knew this was the plan all along.) I told her sure she was welcome to stay and offered her something to drink. ( being friendly and polite) she had a lot to say. Asked all about my family lunch and she named everyone that was there....etc. after gifts she asked were I put my gift from s3.5. I told her I had not unpacked it yet. She said oh, you did not come home after you left my house? I said I had, but had other things to do.( the gift from "him" was a pic in a nice frame) she stated, "oh, I thought it would look nice on the mantle in this room." Etc.etc.
I mentioned family that would be coming by as they passed through town. Told her it would be about 30 minutes. Well, she made her way to the door..quickly, as if trying to get out quickly. I wLked her to the door as the boys played, as she closed the door, I called her name and opened the door. I looked at her in the eyes, with a smile, and said...Merry Christmas. She looked at me and said merry Christmas and as she did, puckered and went to blow a kiss...stopped herself as soon as he hand got close to her mouth ( like she realized what she was doing) and smiled as that hand went up into a wave. Hahahah, standing 6 feet from me was this person, so unsure of her actions that she did this???? WOW?
I feel she is lonely, reality is setting in, and misses me. I am letting her come to me. Not inviting her. If I want to do something, I am direct. I never offered to let her come over today, but she came to me, and I allowed it with open arms and was simply polite.

Thoughts?.
