I've been married for 16 years since highschool and have two kids. Due to my families situation my mom and sisters lived with us for a year or two here and there. In the past, I had no problem with my husband staying up late and watching movies with my sister or even go out together to movies and stuff. I was pregnant with my second child and at times I would be tired and go to bed early or didn't feel like going out. They always kept each other a great company, they both drink, laugh together, listen to one another's stories and my sister always seeks his help in many things. There has never been anything between them but I guess as my husband says he started to have feelings for her over the years. One time I caught him seeing her pictures on the computer and that's when he had to admit he likes her. He also confessed he had masterbated with her photos which he sneaked on a memory card and he was very ashamed of himself and was very sorry. He tried to read different books of how to fall out of love and etc. He's a great husband and a great dad. He has never been with anybody but me. So as time went by he stopped trying to ignore and keeping his distance but instead I believe he started doing things that actually makes her impressed with him. For example he works out everyday and he became muscular because my sister is obsessed with muscular men. If she asks him for a small favor he goes far and beyond and spends hours of his time trying to help her when he can just do it in 5 mins. He always tries to please her and make her happy and appear as a nice guy. He always wants my whole family to be with us when we go on vacations. He booked our last vacation with her without me knowing even-though I had told him we will not go on a vacation. I have a lot of angers towards both my sister and husband. I don't blame my sister a bit but I still react to her and this has affected my relationship with her. I know she only sees my husband as her brother. We see each other almost every weekend and it just burns me when I see husband talking to her or when he looks at her or in a way checks her out. He always checks to see if I'm looking or not before he does that. Do I need to talk to my family about this or maybe his parents. Is this something I have to keep a secret. My family see me sad when they are around but they don't know why. I stop talking to him or even sleep in a diff room for weeks but he seems to get colder. He keeps saying to me and our kids that Mommy hates me. Plz help.
