So, I've had a bunch of issues with my dad stretching WAY before I even thought about getting married, but since the wedding planning kicked up he's been a total a**. He and my mom are going through a nasty divorce, and he has decided that he's not coming to my wedding and doesn't want to be involved with it in any way.
My fiance's parents, though they get along well with my mom, have never met my dad, and they don't really understand why. So today, my future MIL asked me to invite my father out to dinner with them and my fiance and I sometime soon (since they're moving out of town next month and won't be back until the wedding in October).
I tried broaching the subject with my dad, and he flipped out at me. He said that he had no interest in meeting them, and that I was wasting my time trying to include him in any wedding things because "my marriage was doomed to fail just like his did." I admit that I lost my temper and called him selfish, and then he said both my mother and I could go to hell.
At this point, I don't even care; I don't want him involved in my life in any way and I'm glad that he doesn't want to come because he would just make a scene. But the problem is, my future in-laws just do NOT understand this situation I'm in with my dad. They are genuinely nice people who would never say or think anything bad about anyone, and I don't know what to tell them. My dad is not a good person. I accepted that a long time ago, but I don't know how to get that point across to them.
Any tips?
