Is it wrong that i am sleeping with my girlfriend but no at 17?

You are a stand up guy for not taking advantage of your girlfriend during her time of need. If she wants to have with you, I'm sure she'd let you know. You are doing exactly the thing that every boyfriend should do, in my opinion. You obviously care for this girl a lot, or you wouldn't be comforting her the way you are, and so respectfully too. It's completely OK not to have . Abstinence is better than having for the wrong reasons, or selfishly as well.
