Uggh was going through some stuff and to put it away and came across a valentines card saying I was the best husband and she didn't know what love was until she met me and that she loves me more and more each day and would never stop loving me.
Why bother writing it if your according to her so unhappy. This is what makes me think that her meeting this OM is what's driving all of this rather than the crap she spouts out about how bad our marriage was.
I suspect it was not long after (March) that this OM declared to her he had feelings for her (they had been texting as "friends" since Jan).
