HELP. PLS, Is my dad cheating on my mom??!!! Signs of cheating!!?

I would have a family meeting. Maybe you should suggest family counseling to your parents. If you've never had a family meeting tell them it's time you had one. Tell both of them your concerns and it is important your parents are intimate even though it's gross and they might feel like it's none of your business. You could go excercising with your mom or tell her to excercise or not let her eat bad crap. Tell her she's fat. Straight up. Tell her she needs to do something about it because you love her and you're worried about her. Maybe she needs to kick your dad out if he is cheating. He needs to know what he's doing is bad. Remind him he'll go to hell for adultry. He needs to work it out with your mom. If not he can get out and live with the chick he's sleeping with. best wishes
