What I have to say is similar to Suki...

You are correct! This is definitely a YOU problem!

Why is it okay for you to have slept with other women but you cannot get past HERS?

Do you feel 'inferior' in some way (like you are being judged/compared to them?)

If you aren't going to get past this, let her go! Your insecurity will only eat away at the relationship.

I DO have TWO questions:

(1) If you want someone who has no past, why date someone who wasn't a virgin? No matter the answer you give, you will answer your own question.

(2) Why is this coming up NOW? I agree with Suki, it sounds like you may be trying to 'sabotage' the relationship (subconsciously).

My advice to you is seek some professional help (but just for yourself). As you have stated, this isn't HER issue so she doesn't need to be subjected to therapy (if she WANTS to go with you, GREAT!)

Try to concentrate on the fact that you found someone who loves YOU, not anybody else, and take some solace in THAT! Love is hard to find (trust me on THAT) so don't let your petty insecurities stop you two from being happy, okay?

Good luck to the two of you! Hope you can work it out.
