Idk what to do!! Please help!!?

Ok,so I'm 11 and my parents are divorced and I'm glad they got a divorce because when they were married they would either be at work,asleep,or out in the garage talking but when they were awake and in the bed the door would be locked or they would be havin sex. Around '08 they got a divorce because my mom cheated on my dad. Around '09 or the beginning of '10 they got remarried and December '10 they got a divorce because my mom had sex AND cheated on my dad again. Now they are just "friends" and my dad told me my mom asked my dad out and I broke down crying because I HATE my mom!!!!!! So bad!! And he won't listen to me I told him not to go out with her but he just says" we will let god lead us" and I get all pissed and I tell him over and over again DON'T GO OUT WITH HER!! we had lunch with her today,ugh. I've even tried thinking of committing suicide but I just need helppppp!!!!!! Thank u!:)
