Am I being crazy here? Dp & his dc's mother

[Tensery]

We bumped into my dp's dc & his mum today at a soft play, dc is a teen he was playing with younger sibling.

The mother was walking around lots as has a young child to chase after where as we were sat down as ours is of an age to play by himself.

Dp was looking at his ex a lot, a hell of a lot. To the point where I only noticed because of how much it was.

I've never had a bad feeling about it, so no reason to ever think anything. But honestly it was really shit to see, made me feel so unwanted and then question what was going through his mind as he looked at her.

He even took a picture of... well his dc supposedly but it was mainly a picture of her as she was in front of him so it was 80% her and 20% his dc.

I don't know if I'm reading into things unnecessarily or not

I think the weirdest thing here is that you didn't go and say hello. Did the kids not want to play together?

Oh well that was another thing i mentioned, there was no hi from her even though she walked quite near a few times. Im 9 months pregnant so wasn't about to go out of my way but would have gladly initiated if she was near enough to.

Oh yes the kids played together some of the time
