My fiancé and I have been together for 5 years. He is 15 years older than me.. He is such an amazing and genuine guy, our friends and family approve of our relationship and what not... Except for my big sister. She is the only one who is so negative about it, tries to find every wrong and flaw in everything he says or does. I'm sick of it and I think it is totally unfair because she claims I made life changes all because of him, when really it was just for my own happiness (such as not finishing fashion school because I got bored of it, changing my major before, and now doing real estate) she doesn't believe me when I say I am truly happy... her only reason for not approving of us is because of our age difference! Nothing else! She's never around to really try to get to know him like the rest of my family has. I want her to be my maid of honor because she is my sister and I love her, but I don't want someone to be my MOH if she is not happy for me... because I feel like she won't really be genuinely excited and happy about planning the wedding either and since she has this kind of attitude now, who knows how she will behave during the wedding planning process. Thoughts? Has anyone been in this situation? What do you feel I should do? She is expecting me to ask her to be my MOH.
