So..I need Help..

A few years ago I met this girl in Thailand. We were both tourists and was trying to enjoy a peaceful time in North Thailand close to the mountains. We trained together at the same muay thay gym and hanged around together all the time. From day 1 I pretty much laid all of my intentions to her from my actions and put it in my mind that I wanted her.

Days went by, we got close and I thought my chances were getting high to go to the final step. One day all the people from the gym went to a party and I thought that was finally my chance to make a final move. We danced, drank and enjoyed the time together.. at the end of the party we were leaving and I asked her if she wanted to get high before going to bed (she already smoked b4 with me), she agreed and went to her place there, I got my bike and went to my place to get the pot. When I got to her place I put some music to get the mood and we smoked. After that I just jumped in bed with her, took out her dress, untied her bra and took her panties. Everything felt great for me, I really believed I was gonna score. We were both high with such a good music and naked at her house but for some reason everytime I tried to kiss her she neglected me. At first I thought it was cute but my next tentatives were all failures, she definitely did not want to kiss me and this kind of bugged me and I lost all confidence to go on. At the end I stopped and just asked her if I could take a nap that I was tired. Woke up got my bike and moved on but the question still lingers inside of my head. Why she didn't wanted to kiss me? I thought about everything if it was my problem ( bad breath ) if it was her problem ( she did not want me to fall for her ). The mood seemed pretty good and it just turned into a failure for me.

I know the story is not that well written so if anyone have any doubts about the situation just ask me that I will answer.

any guesses anyone? has something happened to some of u before. I am not a Don Juan in no way but I'm not naive with girls, got my share with them and this is the first time something like this happened.
