Seriously....How can I faze out their Mother so I can take over her roll? My boyfriend is still married and?

It'll never happen! Why would you even want to try and make a relationship with a cheater? Honestly, what makes you think you are so much better than his wife? Obviously you aren't or he would not be living with her. He is making a fool out of you! How dare you judge her as a mother! Seems to me that a good father would love and cherish his wife and be a good role model for his children! You will NEVER take her children from her and you my dear, are heading on a road of self destruction! Stop wasting your time with married men, grow up and get some self-respect!
