My parents do not get along well. My dad is constantly hiding texts, leaving the room to take phone calls, and not answering his phone for hours at a time, when he has it on him constantly. He will suddenly close out of apps if anyone walks up behind him while he's on his phone & my mom honks he's cheating on her. And by all accounts of his behavior, I'm inclined to agree. My mom has completely changed in the past couple years, going from a fun vibrant woman, to one more reserved. I'm not sure what to do. He acts like he's done nothing & calls her crazy, but I can see it too. She extremely upset & I try to be there for her, but idk how to help anymore. It makes me sick & makes me hate him a little, because regardless of whether he is actually cheating, which I believe he is, he still doesn't pay attention to her. I know she is feeling neglected & Im not sure how to help besides hugs and words of comfort. I'm 19 & he seems to act more childish the more I watch him. I can't think of any other reason for his behavior. I'd just like some advise on how I can help her. He's screwed with my views on "the happy marriage" because while everything seems perfect on the outside, it's definitely not of you see everything up close. He's never physically abused her, but he can be verbally abusive, commenting snidely about her weight, which she has been trying to lose, and stuff like that.
