Input: Some backstory: I dated a girl back in 2016, let's call her A. We lived together fairly early on, and shared an apartment with my sister and her girlfriend. My sister and A got along well, but as far as I knew weren't best friends. Generally, my relationship with A was rocky. I had just come out as lesbian and this was my first actual relationship with a woman. Looking back, I realize that I was so excited to explore my newfound sexuality that I settled for the first woman that seemed interested in me, and that was definitely wrong of me to do. We moved in together out of necessity (her mother, who she previously lived with, skipped town and left her homeless). I went to school and had a job and it seemed like she didn't want to much other than watch TV, play video games, and stay at home. I felt like I had more of a lazy friend than a girlfriend. It isn't a relationship I look back on fondly. After about 9 or so months together, I decided it wasn't the relationship for me, I wasn't happy in the slightest, and it wasn't going to work out. I broke up with her, and she moved out of the apartment and to a different city about 2.5 hrs away. She would text me occasionally, making sure I definitely wanted to break up. I definitely did. Eventually, I blocked her. I thought that was that. 

Fast forward to a couple months ago. I get a message from my sister asking if my current girlfriend and I would come to a 20-person surprise party she was planning on throwing for her fiancee in March. I say of course, count us in. After all is said and done, I get another message: "Don't h8 me but A is invited too". I was a little blindsided by this message, as I wasn't really aware that they were still in contact after A and I's relationship was over. I replied "If you want her there, that's your decision. But my decision is that I'm not comfortable going if she goes. It makes me uncomfortable, and it's a weird situation altogether for both me and J (my current girlfriend)."

Now, I didn't mind not going to this surprise party. However, she then told me that I was going to have to get over it, because A is coming to her wedding (happening this summer) as well. The wedding is also going to be small, about 50 people so they can convey an "intimate feel". I feel I'm put in a bad predicament here. On one hand, I don't want to upset my sister and demand that she change her guest list so that I can feel comfortable. But, I want to be able to have fun. I also don't want to cause any sort of drama with my current girlfriend.
