Hi,
My sister-in-law estranged herself from us when we had children (over 10 years ago). She wasn't able to have children herself and didn't feel that she could have anything to do with us anymore. This has upset her parents very much and also obviously, my husband. She is now in a different relationship and is getting married. My in-laws have invited us to her wedding (they sent out all the invitations). They say that her husband-to-be wants to meet us and they really want us to come also. My husband has asked them if she really is keen to have us on her special day, as she hasn't seen us for so long, never met the children and hasn't contacted us herself at all. They say yes. We are going, however, I am apprehensive. How should I handle meeting her and introducing my children?
