15 years old SS after living with me and DH for over few years decided to move back to BM. DH tried to convinced SS and also tried talking to BM, but BM is psycho. When SS declared he wants to move apparently because he felt he was not happy, even thought he had loving house, everything was provided, he moved within a week. DH had to pay for everything except flight which cost BM like $50, but it cost us $300, cause SS had a dog so to fly a dog cost $$. When SS lived with us, BM did not pay anything as child support and DH talked to BM and she said she won't ask for child support.

So, SS has been living with BM for over a week, apparently living in the living room on the couch, where he had his own room here. Now SS has called DH to open the account for him so he can have $$ for lunch and school bus. DH offered and pays for SS cell phone and health insurance.

I understand that DH has some sort of obligation to support his child, but how can you teach SS consequence of moving with his BM and that it is now BM responsibility to provide lunch and bus money?? I am afraid SS sees as a bank account but at the same time DH does not want to loose his son over $$. But i think there is a line somewhere, SS has disappointed us and hurt by deciding to move. I am thinking BM is manipulating SS and he is learning that from her. DH does not want to talk with BM, cause she is psycho and somehow he is afraid of her, not sure why.

What to do???

I appreciate any input!
