Wedding do tend to bring every issue and conflict out into the open. I am a big supporter of weddings for that very reason, tbh. It’s best it come out now rather than later. If a couple can make it through the wedding and still be happy and in tact, they’ve got a fighting chance for a life together!
My user name here reflects an issue from my wedding that I blamed (superstitiously) on my marital problems. I was naive and didn’t know about tradition, which allowed for some bad drama to screw up my wedding.
I now you and your fiancé are very much in love. Love conquers all! We’re all rooting for you here to make it through and have a very happy and healthy future together!
