I am weird for acting like this?

My mom and dad aren't together anymore . Its been 8 years now. I'm 18 by the way. My mom has had (of what I know) about 2 bf's. At first I hated both of them mothafuckers. I would cry when I was younger (10yrs old) because I love my dad even though he mistreated my mom and was an alcoholic. But now like today, she's been hanging out with her friends (women) and she also haves men friends. Every time I see them I "dogg" them, ignore them when they try to say hi, I know she's going out with one of them and ****. I always tell my mom why does she go out with losers, cuz I make more money then them , I tell her "aren't you too old for this, she's 43.. "How many more bf's do you need" stuff
