My SD is 22yr old and the only time she will contact my DH is when she wants something or is trying to get information for my SIL who my DH has cut all ties with do to drug use and abandon her own children. My DH has not really had relationship with her do to he didn't know about her until she was 18 and she contacted him. I try to be supportive of him trying to have some kind of relationship, but I'm getting tired of her being such a brat.I was handstitching bibs for her son who was born in December. Right before I was ready to ship them she informed us shedidn't like bibs and was throwing them out, so I gave the bibs to a friend of mine who had a baby around the same time. SD threw a fit and has not talked to me since. Then she had ask us to refinance our home to send her and her husband $10,000 to help catch up their back house payment and when he told her no she didn't talk to him for 6 months. Now his sister is living in the same state and trying to make trouble for my DH. He does have a felonywhich we have never hidden from anyone so her trying to exploit this has backed fired on his sister so now she is using he DD to get more information. I know he wants a relationship with her but we both hate how he is being used. DH has multiple seizure disorder that is controlled by medication however he has break threw seizures when under a lot of stress, which with all SD crap he has had 4 so far this week alone. How much longer should I let this go before trying to convince he his DD is not worth it or set ground rules for him to have relationship with her?
