Irritating Co-Workers Talk Prenup To Me

So here is how the conversation began. My co-workers girlfriend came by and dropped him off some lunch. After she left I told him that after my wedding I am going to be bored, so I am just going to go ahead and plan their wedding. (Funny Ha Ha). So him and I always joke around, he is one of those guys that I know back in the day I would have hung out with. So anyways he told me, "I will get married to Tina when you sign a prenup for Mike." I laughed of course and then that's when the irritating co-workers opened their big fat mouths! One of just kept saying "why wouldn't you sign one". Then the Queen Bitch of the office who is 40, divorced, no kids, and is with a guy who will never marry her says " it's just being realistic". That just pissed me off and I told her she was just bitter:) I just think that a marriage is such a sacred thing and to me the idea of signing a prenup is just like saying well okay we love each other, but since I have more then you financially I have to protect MYSELF! Myself? That is so selfish. I think the whole point of marrying someone is because you love and trust them with everything you have. I just think that the whole signing of the prenup taints the marriage. If two people are willing to make such a huge step and marry one another then go into it with both feet forward, not holding back, right? I just think some people in this office are stupid and bitter! Well anyway just had to vent a little. I feel much better now. I was going to post a pic of her that I photoshopped with devil horns and a mustache but I can't find it, darn! Have a great day everyone, and would love to hear your opinion on this subject.
