I thikn you have to sit down again and look at each other and say if this is how we are now where are you going to be 5 years from now. Relationships are hard work and if you both can't find middle ground when you communicate because someone is holding back for whatever reason that is not fair to either of you. Never be afraid to be single or worry about what will happen if we no longer cohabitate.

On the bright side it is good that you two found these snags now before a pending engagement or marriage!

There are a lot of good books on the shelves about M/F communication in relationships. "Tantric Secrets for men" is a great one, but she and you have to be willing and open to personal growth.

best of luck
