2) I can't make her love me and I can't make her like me, but she will have to tolerate me for the kids benefit. She can't sit there and say she wants to co-parent and put the kids interest first and then bail out for selfish reasons. I can already see the start of problems on the horizon for some holidays and shared events. I want to do whats best for them and I am prepared to pick up the slack, but I felt this and future shared events may need some tough love.
TF, I am in a very similar sitch and foresee problems on the horizon for future holidays and shared family events. I have come to the realization though that her relationship with the kids is exactly the same as her relationship with me and letting go of that I think is key for you. You need to employ the DB rules here as well. You and I and everyone on here knows whats best for the kids. We can't make our spouse love our kids or want a strong relationship with them anymore then we can make them love or want to be with us.
