John,

I am curious what do you plan to say when you do talk to her?  I wonder if you do plan to ask/tell her to move out and if so, when?   That is the bottom line isn’t it?

You say you don’t want to blindside her but you have sharing this with us for months.  Have you shared anything about how you are feeling, how the two families are incompatible, how you are not in love with her?

My take is that you will keep drawing this out and doing her a disservice unless you tell her.

Mark
