I was recently asked what advice I'd give my boys about women and dating when they were old enough. I'm going to C&P my response. It may not be totally fitting, but if what I paste below describes how you feel about her... I'd say go for it... but be smart... be protected. And by all means, make sure that she is emotionally with you through this decision. This is a big one for any young person... and for the girl... it's even a bigger deal. The reason I'm sharing this with you is for her. Because it is likely such a big deal for her, if you don't feel like the description below... let her share that experience with the man who someday will. And I'll admit it... I don't know you from Adam, but all of this is what I would tell my own boys when they are your age.
Here's my response to "What other advice would you give your boys..."
When you find a woman for whom you are willing to make an absolute ass of yourself... and if that woman should seemingly cause your head to open up such that your brains spill out whenever you are around her... and if that woman can give you crap like none other... yet all you can do when you think of her is smile... You then, and only then, will know that you've found 'the one.'
I pray that you should ever be so lucky to find this woman. She does, I promise you from the bottom of my heart, exist... And I pray that when you do find her, you do everything in your power to hold on to her for dear life, for she will be 'the one.' And once you've found her, make it your responsibility, and even more importantly, your pride, to give to her two-fold what she has given to you. Do these things, and I promise you that you will never have a fear in the world. This is my sincere hope for you, my sons.
I sincerely hope that you find piece in your decision, either way.
Regards,
