My wife wants to separate

[AJW]

niceguy,

I'm brand new here but have read through most of your story here and sympathize. My wife is mostly just a presence in the house but not actively trying at our marriage. She's been building relationships outside our marriage for some time and some of it just recently came to light. She seems to be staying for our daughter and because she's afraid of social stigma if she leaves. I've also stood my ground and said that if she leaves that's her choice but for our daughter this is our home and I expect her to be here where there's familiarity. My wife supposedly has not been dating/sleeping with the OM, but she works with him and I know they talk frequently through social media, etc. She's made our marriage issues public knowledge to all the single, immature work friends she has.

I'm devastated, but trying to work on this divorce busting stuff. So hard...
