Hey I Need Some Advice Anyone?

OK i need some advice on this... its kind of a long story but ill make it short as possible.. me and my gf have dated before. but we broke up and got back together a while ago, and we opened up and told each other how we feel and let are emotions free, and we both felt the same way! so we have been hanging out, and recently i told her i loved her and looked her in the eyes she replied the same back, so i told her how much she ment to me and she did the was happy and expresssed herself to me aswell then a few days later... i found out she has been telling people she is single and as well my friend found her on a dating site, so like i dont no what to do... she tells me she loves me we no how we feel about each other. and now shes in a pissy mood and wont say why, and doesn't wana hang out, and has been hangin with some friend, which i shouldnt have to question cuz im not a jelous guy but it seems like she is gettn distant, after we had talked and finally got back together and shared are emotions.. any advice anyone? i need some feed back. ps i no i have to talk to her but i want to in person not over no comp. i think thats stupid cuz ppl have time t think of what they want to say...
