I do the same with my blackberry storm. I post from time to time from my phone like you from where ever I am.
Try to enjoy the evening. Get some good conversation going with some people. I understand what you are saying about another woman feeling like you are attractive. Its a good confidence booster. But in the end, the only one you really want to feel attraction for you is your W. So try not to think about if another woman feels it for you because if you noticed that someone did, in your state of mind and loneliness it could turn into a temptation that you would regret even though you say you wouldn't do anything.
Just enjoy the company and the fact that you aren't sitting at home alone. Take in the evening for all it is worth. You will have plenty of time to actually be alone later. Make the most of your moment now.
