Hon, I agree with the other posters, it is best you found out after two dates. It could have been far worse. I moved in with a couple - at her urging - everything was beautiful, until with no explanation she went 180 degrees and everything blew up. I won't bore you with the painful details.
That said, this kind of insecure, controlling, I don't want my partner to be happy unless I say so crap eventually destroys relationships. After a year and 2 marriage counselors, the couple I was with is divorcing. Does it bring me any satisfaction. No. Everybody got badly hurt in the end.
I know you are sad, but you dodged a huge bullet.
