Re: The 'No Sex before Marriage1 type of girls
That's something you need to take time to figure out. If a girl hits me with that line, and is sincere, I would respect it. If I don't see myself getting married to her, I would drop it just to not "lose myself," you know?
That said, I've been in an LTR where my ex was adamant about waiting until marriage. I was ok with it and respected her decision because I did see myself settling down with her. Then again, she was (is?) a virgin.
Back to your girl! If she's a virgin, respect it and go separate ways. If she's not, well...grab a condom. Or twelve.
My view is that if she's had sex before, I won't buy that "waiting until marriage" BS. I'll say I understand (or ignore it altogether) and bust (pun intended) through LMR and WHOOPS - "heat of the moment"
Always leave her better than you found her.
