This is tricky! I was kind of confused like you although it was a totally different situation. I was worried about making the legal day feel too "real" and I didnt want it to take away from the wedding in Mexico. I am doing the legal stuff quick and painless, just signing papers and no celebration. I want Mexico to feel and be like the real deal wedding. But that is just my opinion! You have to do what feels right for you! Because of your godfather, I see where you are confused. HMMMM......
I think for once you need to put what YOU want first! Years down the road you dont want any regrets about your wedding. Its the most exciting time in our lives! You want to be able to tell your kids or grandkids your wedding story and have a happy face on! I know its hard, but I just think its time to put you first! Good luck!
