My boyfriend's sister and I don't really talk,unless it's a family function. I don't like it. I really want us to be friends and talk more often. We're cordial to one another when we need to be, but we still don't say much to each other. It's so strange. When I first came into the picture, things were fine. Then a few things happened where I wasn't very nice to her and she kept me at a distance, which I can understand. We were very young when this happened. Since then, I've turned my life around and changed drastically. I still have my ways at times, and so does she. I've apologized and we both decided to move past it and get along. Now, just recently, she's been acting a little 'fake' in my opinion and it's really hurting my feelings. I thought we had moved past it all. Seems like our relationship reverted. It sucks. I'm really thinking about texting her and inviting her to lunch one day so we can sit and talk out whatever it is that's going on between us. I love my boyfriend dearly and I also love his family. I just want to be positive and get along with everyone. My question is, how should I word my invitation to her? How do I set it up?
