Wow, I certainly sympathize with your situation. I am in a similar one, except it's my boyfriend's family that does not like me. I think that if you love him and respect him and your relationship, you should stand up to your family and communicate that you're happy with this person and they should be happy for you. I know it's tough, especially when family is such an important aspect, but seriously, if they can't respect your decision to be with someone that you feel treats you well and loves you, then that's their problem. It's different if the relationship was abusive or detrimental to your mental/physical health. This puts an unnecessary strain on both you and your fiance. You two are having the relationship and you should know what's best for each other. I agree with the other posters--they are trying to manipulate you into seeing someone they like, rather than someone you like. And that's sad because really, that decision is yours to make. It would be GREAT if your mom loved him but the reality is, a lot of people have problems with their in-laws. Good luck and be strong! You know what's best for you.
