Oh my goodness, she is definitely putting oyu through the wringer emotionally.
Yes, I agree totally with your boundary.
I think the possibility of an OM is good in a weird way b/c you know that it really is on her end- the demise of the marriage.
As for your 13 son calling another man "dad"... Not a chance in this world! I was a D kid- as a teenager- you usually can't stand the OM or OW. My hubby works with middle schoolers all day long and they complain constantly about the OM, OW, step-parent. Seriously he hears this alot. I think it is rare for there to be bonding once a child is older, IMO.
3 months- ugg! Can you have a count-down calendar, maybe?
Sorry for your personal hell.
