my step daughter aways gets her way! she is 18 and should be out starting her life but has been trying to split me and her mom up from day one ! She says all she ever wanted was a dad but that is not what she wants she wants somebody that will bow to her and let her run her mom's life. I got hurt 3 years ago and lost my leg ,my girlfreind was my rock and i love her. about 6 months ago I went on new pain meds and started drinking real heavy and lashing out! the side effects of drugs are agression and mood changes Girlfreind waited it out till we had a blow out now I am getting help. I quit drinking and the pain meds now the 18 year old is telling her mom she is not allowed to be with me . that she is choosing me over her and crying eberytime she trys to talk to her . me and my girlfreind are fine now we are best freinds and love each other so much . How can I make my step daughter stop metally abusing my girlfreind .and how can I make my girlfreind see that she won't lose her daughter by being with me? If she does then the daughter doesn't really love her that much does she?
