Advice Please.

Ok so what do you ladies do that have been disrespected by your mans family ? Does he stick up for you or let it continue to happen? I'm asking because my man has let his sister disrespect me so much in the pass two weeks that I'm seriously thinking of filing harassment charges. I've asked to be left alone multiple time but she refuses. I seriously thinks this may end our relationship and we'll just have to co-parent. 😞
