Tonight my close friends are having a special together that I want to avoid because my ex will be there. I don't know how to tell my friends and make everything cool at the same time.
Backstory: My ex is this girl I've had a hard ass time getting over. She was quite easy on the eyes, and was super charismatic. She broke up with me about 4 years ago, so it's been a long time, but there is more to this story.
About a year ago, we saw each other at a party, and talked, we exchanged texts later, and eventually hung out. I thought things were going pretty cool, and maybe we'd be able to get back together, but I was just trying to play it cool.
One night we were planning to go see a movie together, and a day before we went, she texted me to pick her up and pay for her movie since she was considering it a date. I was like: "ok!"
.
After the movie was over, I took her home and discovered she called the night a date just so she could get a ride and a free movie ticket. I was crushed, and super humiliated, and I just left without saying anything.
That was the last time I saw her, so even though this happened a year ago, there's no way I can be in the same room as her and be cool about everything.
Not all of my friends know about this, and the ones that do don't know how deeply this hurt. I don't know how I can tell my friends that I don't want to go without looking like a big baby. I mean, I know this is a little immature, but I just can't go tonight.
What should I do...
