Tangled, indeed. As for what support she is getting from the other guy, I am not sure. I cannot get anything resembling a straight answer out of my ex as to why she is doing this.
Our current support situation is zero-sum, as she and I each have custody of some of our children. I have no intentions of revisiting the issue to account for one of the ones living with her not being 'mine'. Since we live locally to each other, I still see all of them on a regular basis, and it is my desire to continue treating my daughter as I always have. I buy her gifts, include her in family outings to the movies and such, and if I see her shoes are a bit worn, I'll drag her into a shoe store for a new pair; just like always.
Time will tell what my crazy ex has in mind. All I can do is keep being me.
Well, I'll say it again...you're a good sort.
"and if I see her shoes are a bit worn, I'll drag her into a shoe store for a new pair"
HAHA, In a couple of years when she's older she'll be dragging YOU into the shoe store! :)
