To cut a very long story short - a long time ago I shared a house with a girl I originally got on quite well with. For most of the time we knew each other, I was single and she was not; no dramas.
When I met my (now) husband, she was initially quite happy for me - however, when he proposed, it happened that her on-off boyfriend left her and she completely changed - alternately not speaking to me and being very aggressive when she did. Her mother wrote a particularly nasty letter to me at the time accusing me of getting married to spite her daughter and hoping I got divorced - all very odd. I moved out and housemate announced that I was never to darken her door again.
Fast forward 10 years, and suddenly former housemate contacts me out of the blue to invite me to her wedding. She's made no reference to what's gone before, and part of me wants to attend if she is making a genuine attempt at burying the hatchet (not that I know what I did to upset her originally) However, I'm due to run a marathon the next day and it might not be a good idea for me to have a long day out at the wedding.
I'm a bit worried that she might see this as a poor excuse though - DH is convinced that she just wants extra bodies at her wedding and won't actually notice if I'm there or not. (I'm not relishing seeing her mother)
Would it be wrong not to go? Or should I go for the ceremony and go home early? It's about a three-hour drive away so the second option would still be a significant one.
