brother in laws gf

Have to rant I learned never to try to protect people I love. My brother in got a new gf. There both going through a divorce. She was staying with her with her kids supposedly got kicked out a month into there relationship. She and kids moved in with him. She was over at my house 2 days ago and basically tells me she lied to him about not being able to have more kids. Well I told my husband who then had a conversation about it with him. He got pissed at us and told us he hates us and stop trying to ruin his relationship. This is the first time we've ever said anything about there relationship. I just didn't want him to get trapped. Now cause he confronted her and she denied ever saying that to me were the bad guys. Seriously never going to help anyone out ever again. He seriously knows how to pick them. Rant over
