BM is such a POS
DH figure that the reason BM dumped SD18 on us is because she got expensive.
BM pays no CS. BM has told SD18 that she won't contribute a dime to SD18's college expenses unless SD18 moves back to Louisiana, goes to a full university, and joins a sorority. Can you say, "living vicariously through your child"? I knew you could!
SD18 is pretty disgruntled by this. BM sends her younger child to private school at a cost of $3500/year, but can't handle 1/3 community college tuition at less than $1500/year. It just reinforces that SD18 is only worthwhile to BM as long as SD18 is her little puppet.
The woman is f-ing useless. DH and I will get SD18 through college (provided she work at it and make the grades) and it will reflect on US, not BM.
