My sister is married to an extremely controlling man. He wouldn't even let her invite her own family to their wedding because he insisted on just eloping with just the two of them. She went along with it because it was the only way he would marry her. My sister and I are best friends, but she unfortunately has a very low self-esteem so she basically got with him because she felt she didn't deserve better. Anyways, her and I had lunch yesterday and she informed me they are trying to get pregnant. During the conversation, she mentioned that if she is pregnant or has a baby her husband isn't comfortable with her attending the wedding. He would worry the wedding would be too much for her to handle if pregnant. He also wouldn't want their baby around loud music and alcohol. He has a son from a prior relationship and he never lets anyone else watch the child so I doubt he would let anyone watch their baby if they have one. I'm not sure how to proceed. I know it can take a while to have a baby, but I'm nervous my sister won't be able to attend. I would be completely devastated. I'm not sure if I should prepare myself now that she might not be there or if I should continue planning as if she will be there. Any advice?
