His and Her Health

Me and my girlfrien have been together for 8 months we have had no sex for 2 months not even sexual intamacy(touching etc..) and we had sex once the month before. I have tried talking to her and all I get is I don't know. She did finally breakdown and say she was depressed but I feel she said that just to give me a reason. I love this women and no sex isn't the most important thing but she doesn't let me know in any way that she is attracted to me. It's a very early relationship and I feel a big loss of not just sexual intrest but a loss of any type of intamacy. I've cooked a romantic meal, with candles and even wrote her a poem and all I get is a peck on the lips and a thankyou. No real appreciation or grattitude shown. I do not know what to do????
