Should I disconnect from my family?

I am now in a 2nd marriage. If he is not abusive to you in any way, and if you love him, two years after a divorce is not too soon to be involved with someone else. I can't speak for your family, but life is way too hard not to go through it with someone you love and loves you back. If you know your family is that way, don't give them an opportunity to hurt you or your fiancee again by inviting them to family gatherings involving the two of you. However, when it comes to remaining in contact with your family, someday you will be very glad and proud you took the high road and maintained your dignity. Treat them with respect (even if they don't deserve it) and with care--take care of your mom if it's "your turn"--and, if need be, limit the time you are in their presence to holidays, special events, etc. But, definitely refuse to debate your fiancee with them, even if it means changing the subject 50 million times in one conversation.
