They were engaged..that's very serious. Some people can't get over that. My sister was almost engaged to a boy once and three years after the fact it still bothers her. Not in an immature way where she won't see him, they're friends, but he recently got married and it was hard for her to handle it.
Well it's not that she's uncomfrotable around him.. she does NOT want him back. She just doesn't like him, and regrets ever being with him. hah. Does that clear things up or make them more confusing?
I think what Lindsay said.. "some people" is on the money. In another post one here I mention my ex-wife. She's DF'ed and our divorce is scriptural. We were married almost 10 years, including courtship and everything, we were together for over 11 years. I don't want her back, but I know if she's ever reinstated, I would want to be at that meeting to welcome her back... but that's me. That doesn't mean I want her back or have a desire for her in that way again, but she will be my sister once again. For some other people it's harder to do... so it depends on the makeup of those involved. I guess just respect her feelings and make it clear that you harbor no resentment towards the brother and that you are still friends with him. If she feels betrayed by you at all, that's her "problem" and she has to live with that...
