He didn't tell me anything about his contact with OW or gave any indication that anything changed....the opposite, he was super nice to me.....
Weird similarity to how my husband acted as he was trying to get rid of OW and dealing in that direction......I, myself, got instruction NOT to confront, but wait it out, and I disobeyed...leading to a totally angry and vindictive husband for a time. Possibly, in your case, it might lead to an even greater distance between him and you, IF you confront.
The difference here is yours not being at home, whereas mine WAS.
Don't be so quick to assume OW will win, Mila, just go on, do the best you can and watch the situation to see what happens.
She is HIS problem, not yours, and therefore responsible for either getting rid of her, or not.
You'll know either way and soon.
As hard as it is, remember that people have to be let go to do what they think is best, even if you KNOW it's wrong.
You deal with the fallout later, however it goes.
I know how it is, having been there, done that. It's not easy, but you CAN DO THIS.
Remember, as each person is different, every MLC/Transition is different..what works for one may not work for another. Most of the time it is trial and error for ALL involved.
