I agree with Sgrinavi as well. You've got to decide what you really want and then go for it. Your personal freedom and the right to make your own decisions are certainly, in my opinion, things to stand up for. Don't back down my friend, you'll regret it when your 50.
I am engaged, I don't plan on competing, but this is something I'm doing for me. The missus wasn't to keen on the idea at first but I love to be big, I love to be strong, I love to workout, and I love to feel good about my physical appearance, so she's willing to accept whatever I want to do. If you love these things too, think about it before it's too late. You may end up with regrets.
Good luck.
