From the U.S.: I have been with my boyfriend for 2 years. I love him so much. He has 3 children, who I get along with very well but recently I find myself resenting his daughter (6 y/o) and it’s causing us to fight. She lies constantly and tells her mother all these bad (and untrue) things about our house which her mom records. It makes me not want to speak with her. She also used to want to hang out with me and do stuff but has admitted that her mother tells her not so when she is with her dad, she acts weird.
When I try to address it with my boyfriend we usually fight about it. Now he and I were talking about marriage and planning to have our own children and I feel as though this is putting a wedge in our relationship. I don’t want to lose him but I don’t know how to get a hold on my feelings. I feel betrayed and hurt but I do try to make things ok. She’ll just say mean things or act weird to me when he’s not around and then try to be sweet when he is in the room — very manipulative. I know it’s partially her mothers doing but I do love these kids and I am so in love with my boyfriend and I want things to get better.
