OK I just read some more of the details that are unraveling,
candid opinion: you can do better. If you're still in love w him, put the wedding off and seek therapy asap. Money is the least of your worries right now.
Keep in mind though, I'm no mushpie, I'm a no-nonsense lady and I don't take BS from anyone. I've dated a multitude of people and seen it all between my friends, families and my own relationships. I'll give you what I think straightup and what I think is that you can do better.
