I think my dad is "eyeing" other women..help please?

Bakugan Pyrus and Ventus King Asked: I think my dad is "eyeing" other women..help please?

My dad is in his 60s and often I feel he isn't grateful for all that my mom does (cook meals, makes most of our family's money, house work, cleaning, etc) I also have seen him look at other women (younger). Like today after church he was staring at this younger (single) woman's butt and then her breasts. I think he was even trying to flirt with her. She isnt the only one. I'm not sure if I'm imagining it, but my mom and I are leaving town for a week and I'm afraid he might cheat on her. idk what to do and if I try and mention it I'm going to get yelled at… He is a handy man and he is always gone except for meals and to sleep. Often he can be rather mean to me and my mom but he still is a great dad other than that. He doesn't drink, smoke, sit in front of the TV a lot, and he'll usually make a little time for family game nights. Am I imagining things? What should I do? I really don't want to bring it up because that could make things really bad and there'd be a huge argument and I don't want my parents to divorce:(… Thanks
