Nursing school graduation

I graduated from nursing school and had a dinner I invited my family friends and my boyfriend and his sister in the past we never really got along because she was always very possessive rude at times & clingy always wanting to hang out be around us (she’s 31) prior to all of this for my boyfriends birthday we went to Miami and she came also by herself .. and me and her got in a huge fight because she was talking about my sister & family and he just sat there. so anyway back to the point I invited her to my dinner 8 plus months later and I gave speeches to everyone and her speech I said through our ups and our downs I do appreciate you for being here and I love you as my sister blah blah blah I said something really nice .SHE took that and said to my boyfriend I pin pointed her out because I didn’t say “ through our ups and downs “to anyone else but her . I really had no ill intentions on saying that it was the truth. Now my boyfriend and me spent the night together out in the city after the dinner that was suppose to be fun arguing about his sister. (Before we dropped her off she goes enjoy the night together don’t worry about it to her brother ) and a week later we are still here talking about the same situation even after I tried to reach out to her apologized and she ignored me . I feel like she purposely tried to make my night about her any advice ?
