Thought I was quite close with SIL. My DB fucked off about 5 years ago leaving her alone with 3 kids. DB is in another country and has just married again, and is completely NC with the whole family. Anyway, me and her were always close, we have a lot of the same interests. When DB disappeared I helped her a lot with the kids. Now she is remarried herself, but still expects me to look after the kids a lot. Basically I look after them most Saturdays, plus about half of school holidays. She only ever contacts me now about babysitting since her dh came along. I do love those kids though and love having them, but it's like she pretends we're friends to keep a free babysitter. None of my siblings look after the 3 kids, and my parents don't bother with them either (she openly dislikes them so they feel really uncomfortable) , so I'm the only member of the family to have any kind of relationship with them. Not sure what I'm asking, suppose am I right to feel used and does it even matter when I still want to see the kids.
