Are you guys freakin nuts? I agree with OV - she SHOULDN'T trust you. You behaved badly. Trust has to be earned, and you didn't earn it. She may be crazy, and she may be controlling, but based on what you posted here, I'd say you contributed significantly to her insecurity.
Also, why are you guys talking about marriage after only 9 months? It's no wonder you should have cold feet. It is TOO SOON. If this girl is crazy, it is merely based on the fact that she would even CONSIDER marrying a guy she's known for only 9 months.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
