Ah! I hope you never have to experience something like that ever again. It’s hard to imagine the way some people think! You just have to be true to your beliefs.
I went through something like this, but with my boyfriend’s “born again” family. They were trying to convert me, so I stood up for myself and from that point things haven’t been too good. They convinced my boyfriend of three and half years to break up with me. They did and said some pretty horrible things to me when before they pretended like they loved me and his sisters pretended to be my friend then turned on me in an instant.
My boyfriend actually was going to church with me the whole time we were together and I think they were “scared” he was going to convert to Catholicism. (his parents both used to be Catholic and both of their entire families still are…it’s strange)
My boyfriend and I have since gotten back together after he got away from the brainwashing and realized what was going on. But his family is still really, really mean to me(especially his mother). I’ve been nothing but nice to all of them and they refuse to have anything to do with me and are constantly saying bad things about me to him. So stressful!!! I’m still struggling with this and it’s been 6 months. I’ve never been more hurt in all of my life.
