Not sure where to start... but about half a year ago my dad decided he wanted to start losing some weight. He started going out every night and claimed he was going to the gym. None of us thought anything of it because he actually did lose about 25 lbs in a month and a bit. After about two months he stopped losing weight and it was clear he wasn't at the gym. He even gained weight but he kept using the same excuse to go out. My mom confronted him many times but he said she's crazy. It's pretty obvious because he's been going out honestly almost every weeknight for months and we all suspect it. Just some background, my mom is 49, dad is 50, and my dad has been working very hard the last few years. My mom lost her job and due to disability is unable to get another one and has been at home for years, and my dad even tried to get overtime hours just to help out. Of us kids, we're 18-23 and in University so we can't really work much. Anyway, today was a breaking point. When my dad came home from work my mom asked him to please stay home tonight just so we can all spend some time together as we haven't in a while. He said okay. After dinner my mom said she was going for a quick shower because it was warm in our house and she wanted to cool off. Literally she was upstairs for five minutes and my dad left. None of us realized he had gone until my mom came down from the shower. She started freaking out, crying, was even throwing things around the house. None of us really know what to say and she keeps screaming, "he's with his other girlfriend!" My mom admitted to me that she looked at his email and saw several messages from a woman but didn't read them. I guess what I'm saying is I don't really know who to talk to about this or what to do and was wondering if anybody else ever had something similar happen and how they got through it.
