Yes I was faithful during the marriage though I'll admit for a few months about a year ago I found myself wondering if I'd be happier elsewhere as I didn't feel like the relationship was really working for me (wife just didn't seem to be able to find joy in anything). I wish I'd acted on it then.
She says OM1 has nothing to do with the breakup and that its because she was so miserable and that my 'bullying, controlling and abusive' behaviour is what made her miserable. I don't agree I was even in that ball park but at the same time a lot of my behaviour wasn't great (basically I sulked a lot) - so I do agree that OM1 was a catalyst rather than cause.
She seems really angry at me but I'd be guessing why, I suspect a combination of things and money being a massive one given what SIL has said. I doubt she even fully knows but she knows whatever it is is my fault.
Both mid 30s, 2 young kids BD 7sep14 XW moved on long ago, now living with OM1 D paperwork in progress
