Hi I'm in a long distance relationship with my fiance who lives 6000 miles away. It's difficult at times but we make it work and love one another tremendously. My issue is my other halfs sister is close friends with his ex gf... I understand there is a bond / friendship there and not too worried about him however I am upset that the three of them are spending xmas day together as the sis invited lots of people to hers for xmas. Alcohol and sleepovers at the sisters aren't making me feel great.
(He always spends xmas with his sister but I'm feeling quite nervous at the idea of the ex being there) am I overreacting at thought?
