I have been in a long distance relationship for nearly two years. My fiancé and I are getting married in September, and we are both excited about our lives together. However, one family issue in particular we are dealing with is my sister. She is my only sibling, who is 3 years older than me. She is not married, but was engaged four years ago. However, that relationship ended in a breakup. Fast forward to where we are now, my sister hasn't really taken the time to get to know my fiancé. While our relationship has been long distance since 2022, my fiancé has visited my family at least twice since we have been together. When she first came, she stayed at my parent's house for a week.
My sister didn't take the time to meet her during her first visit. My sister did experience a brief health challenge during her first visit, but toward the end of her stay she recovered and had an opportunity to at least meet my fiancé and her parents in person. She didn't meet her until the 2nd visit that my fiancé made a few months later. Throughout my relationship, my sister hasn't expressed much happiness or joy for me. When we became engaged last September, my sister never congratulated me with the exception of making a comment on my Facebook post.
My sister and I later had a conversation in front of my parents. We hashed it out, and I expressed that all I really wanted was her support or that she would show some sort of joy. To this day, my sister hasn't shown anything at least not verbally. The only time that my sister and fiancé had any sort of interaction was mostly via Facebook when they were exchanging comments on posts. This happened for a good month. We thought that she was finally coming around. However, after a month, it stopped, and that was because my sister found out from me that she would not be in our wedding party. My fiancé initially wanted to have my sister as a bridesmaid, but I wasn't so enthused. Eventually, my fiancé decided to go with someone else, because she didn't want my sister to be a part of our wedding if she wasn't supportive. My sister found out that she was not chosen and she became upset with me.
Eventually, she and I made amends over it, and I asked her if she wanted to be in our wedding party. She declined. So we left it at that. However, I recently had a conversation with my sister to ask her how she feels about having a sister-in-law. She said, she felt nothing. In fact, after I became engaged I asked my sister how she felt about it, and she said then, she felt neutral. My sister feels that she will get to know my fiancé only because she and I are getting married. But she also said, that she didn't feel a connection with her. Its made me and my fiancé feel saddened by it, but at the same time, we are resolving to put boundaries in place with my sister. What should we do in this situation? My fiancé feels like my sister doesn't like her. I feel that my sister has multiple issues concerning us. My fiancé has been nothing but cordial to her, but outside of the one month of communication, and meeting her in person, she has not shown a willingness to text, call, or maintain contact. Please share your thoughts.
