This is a difficult situation. Your mother did not deal with this situation very well. If she had fears for you and your relationship she should have done the adult thing and discuss it with you rather than playing the immature game of "guess why I'm upset."

You really do have to live you own life and make your own mistakes. As parents we'd really like you to be able to have the ability to learn from our experiences, but that just isn't going to happen in most situations.

For the sake of peace, I would give mom a call and tell her that you're sorry that she's unhappy about your choice of a mate (the issue is hers not yours!) but you are sure that once she gets to know him better you're sure that she'll grow to love him as well. Let her know that she raised you well and that while you respect her opinion, you think she's mistaken this time.
