do any of you have conflict with partners over how you handle things?

I'll try and be brief. I avoid people and situations with babies. My husband doesn't. I haven't spoken to my SIL since about November last year, I posted here back then when I thought she was insensitive about telling us of her pregnancy. She's about 6 months now. There's no way I want to be around her. I said something today (via email which we know is not the best for communication and things coming across the way we mean, though I was awfu in the first instance and then followed up by saying that I still haven't forgiven them or forgotten about that night.) and my husband said don't email me anymore. I'm sick of your attitude.

I know I'm probably to the extreme with my avoidance of situations, but do you ever feel alone and that your partner just doesn't get it? Do they give you grief about things you may do or say? I'm expecting a hell of an argument tonight.
