I have a very close friend that I have known from childhood who is getting married in Mexico 3 months before my wedding. Because hers is a destination wedding, and very expensive to attend, I am not able to afford going so close to my own wedding. She had asked me to be a bridesmaid, and she is one of my bridesmaids. She made me feel very guilty for not being able to attend her wedding, but it is just asking too much of me. I am still helping with the bridal shower and bachelorette party.
The issue is that my fiance and I have chosen the same resort where she is getting married for our honeymoon. Without knowing that it was the same resort, my fiance fell in love with it, and we both have our hearts set on going there for our own honeymoon. We have not booked yet, and have looked at other options but just have our hearts set on that same resort. My gut feeling (and that of my close family that I have told about the situation) is that it is my honeymoon and I shouldn't worry about anything. However, I do feel guilty that I can't go to her wedding, but am going to the same place 3 months later.
My question is how do I tell her this without hurting her feelings or causing drama with her, since she is one of my bridesmaids as well. HELP!
