Would you go to this birthday party?

I was invited to an old uni friends birthday which is out of town. My boyfriend really wants to go on a road trip. I haven't ever told him this story but about 5 or so years ago I got really drunk on wine. I'm not much of a drinker and definitely learned my lesson after this day. We went back to my friends house and I had somehow pooped my pants. I didn't even notice until I arrived at my house. I just threw my clothes in the wash, jumped in the shower and carried on with life. I was due to go on holiday with the girls I was out with. A month later we went to dinner and one of the girls made a joke about what had happened. Then one of them started being very fake and saying we should go out more often etc. (she was trying to cover up the fact they were probably talking about the poop incident before I arrived).The holiday was great, I enjoyed and had no choice but to make the most out of it since I couldn't get a refund. I'm pretty much over it, I haven't seen these people in about 5 years. Now I've written this I'm thinking to not go incase any of it resurfaces. It's not like I'll be missing out on anything. I think I'm just really forgiving about the whole thing. Would really be upset if it came up in conversation though but would be nice to see a couple of my old friends.
