Not entirely sure.
She got pregnant on purpose, i know this now. So the particulars dont much matter. It was a deliberate deception.

Her EX that had dumped her because of her BS before her and i got together had recently had a child. She was trying to one up him somehow. I've come to realize A lot of our early relationship was dictated by her previous one, and where it failed.

As i expect a lot of her relationship with OM has subconscious connections to me. Explains why they have gone and done all things that WW and I had planned on doing before we split. All activities we had talked about sharing with S3 are now being done with her an OM.
She always connects to her previous situations with her current ones somehow seemingly.
