Alright- here's the issue. My FI's ex wife has physical custody of the kids. Up until now, she has wanted for him to have the kids during the school year and her to have them during summer and holidays so she can attend school full time. Recently, however, she changed her mind. She decided she only want him to see them on holidays.
Her reason for this is that because he's in the military, he can be sent on TDY at anytime, which would leave the kids temporarily with me, and she doesn't want that. Essentially, because he is getting married to me, he may lose his kids.
What can I do? I don't want him to have to choose between me and his kids, but that's what is going to happen. His children are very young- 3 and 5, and if this happens they will barely know their father. And even if it is her doing, it is because of me and her personal dislike for me.
And before you ask, there is no legitimate reason for her to not trust me with the children- I've been working with children for 10 years, from being a private nanny to teaching preschool. I have solid background checks, training in childcare, and I know pediatric first aid. She just really doesn't like me.
