I"m sorry you are in so much pain right now. Hopefully you will keep your promise to your T about SH.

As for your fiancé deciding your family can't be at your wedding, that concerns me.. Do you have a tendency to give away your personal power? That can lead to feelings of helplessness and then to self injury. It is YOUR decision if you want your family at your wedding. You may decide that family is indeed a rotten family and don't want them there. But again that's your decision.

Giving birth to a child is an incredibly overwhelming experience. When i had my son i didnt get around to telling one of my friends until a week later. She got so angry with me that she ended our friendship. It hurts to this day. I don't think you were deliberately excluded. Hope you feel better soon
