Social Dilemma: Do I Have to Attend My Sister's FOURTH Wedding?

Today's 98.3 TRY Social Dilemma came from Jake and it's about family and weddings. Here's the email: Hi Jaime. My sister is getting married for the fourth time and though I love her and her husband-to-be, I just got an offer to go on a free Caribbean vacation with my girlfriend's family all I have to do is pay for the airfare. Of course, the vacation falls on the day she’s getting married. Now again it’s her fourth marriage and for some reason, she’s having a big wedding like she’s done for all the other marriages. I’ve been to the three prior and gave her a nice gift for all of them, money I will never get back. Now she’s mad that I won't be there because I’m her only sibling. I think she’s being selfish making me feel bad that I would rather go on vacation than go to her now fourth wedding. Isn’t she the one being selfish here? Then she got mad when I joked that I promised to be at her fifth wedding. I know that was a low blow but let's face it the odds are in my favor. So am I in the wrong here? Thanks for the help ~ Jake. Well again, family is always difficult right? We love our family through thick and thin but that doesn't mean we're always going to agree. I'm surprised Jake's sister is having a big wedding for her fourth, but to each their own. I don't think Jake should have to feel guilty. God bless his sister for finding someone she loves, but it's not fair to everyone in her life to keep asking for more and more and more. That's my take anyway. What do you think?
