My boyfriend and I have been together almost 5 years and we have a 3 year old together. My relationship with his family isn’t the best especially with his sister in law. Ever since she started dating his brother she would always give me all these nasty looks and never tried to get along with me and it’s obvious now that she has a problem with me. Well whenever my boyfriends family has a party or a family gathering she always takes her sister and I notice her sister is always starring at my boyfriend. Well turns out she was asking for my boyfriends Snapchat and number so she can get to know him because she likes him. Ever since then I haven’t really been wanting to be around his family just because I feel a big disrespect from his brother and his sister in law. And I try to talk to my boyfriend about it but he just doesn’t understand. He thinks that I just don’t want him around his family and that’s not the case, I just don’t want him going around because of her. I feel like he’ll eventually fall for her shit and cheat on me with her. He says that I need to trust him and I do trust him I just don’t trust her and he keeps saying that that doesn’t make sense but it does to me. I mean it’s just hard because I’ve never been through something like this and I just don’t know how to react or what to do.
