I was going to congratulate you as well, but after I read you reply... Man!

Me and my guy, we met 3 years ago. After 2 years of knowing eachother we got married last year. Things felt right. We did have disagreements, but nothing compared to what you are writing. We would disagree about politics, some small household stuff and we had to adjust our eating habits. Decision making is somewhat balanced. I like deciding on things, but I can never plan a vacation as well as he does for example.

What you are writing sounds bad on several levels:
1. She does not respect you and your opinions
2. She doesn't want to listen and doesn't try to understand your point of view
3. She is controlling the money YOU have earned
4. She doesn't want you to have friends
+ Probably more things worth pointing out...

If you love her and do want to marry her - do couples therapy ASAP, don't wait until you are married.

If you don't love her and do not want to marry her... It's clear what you have to do
