I guess we have "Irreconcilable Differences"

[NYCPeter]

kml - I don't mind her having a tenant, but having OM move in and I still pay full alimony would be a bitter pill to swallow.
She will be getting more than enough $$ in CS and alimony to live a comfortable lifestyle (greater than 55% of my salary) - if she chooses to invite a man to the home to share her life I don't think I should be funding it.

My W didn't give up her career - she wanted to be a full-time mum. There is nothing stopping her from getting a full-time job, she chooses not to. I will have the girls 50% of the time and give up more than half my salary - (NY state does not take into account % parenting time when calculating CS - just the monied spouse pays unless it's greater than 50% of the time).

So in short - yes I feel justified doing this.
