Okay, so I need some advice. I've been married 6 years now. DH and I have a 3 year old ds and a 9 month old ds. About a year ago my younger sister had admitted to that she had sex with my DH about 3 months before we were married. It was hard to swallow but they both assured me that it happened before we were married and never ever after. What hurt the most, was that my mother knew about it long before I did, but didn't tell me because it "wasn't her place." It took a lot to get over this, and to be honest I still think about it. All the time.
So I just found out that my DH has been paying her phone bill for the past 2 months. Money is tight and he is usually pretty cheap. He said she came to him and asked him for a loan and asked him not to tell me. Why she didn't come to me is beyond me. I love my sister, and I love my nephew, so if they ever needed money I would never say no. It bothers me that she would go to my DH, especially after their history. How do I confront her about this without making her angry? I want her to come to me and respect my relationship with my DH. We already do a lot to take care of her son. Her son and my boys are all very close since my nephew doesn't have a father figure, he spends a lot of time with us and is very attached to DH. I don't want to ruin that for them. Help??
