LGBT poll: I think I'm digging myself a pretty deep hole...concerning women...what should I do?

You sound like a great guy and a great friend. There are a few options available in this situation. One, you could be completely honest and tell them you are gay. If you are not ready to come out yet, which is understandable given the information you provided for your current situation, we can consider another option. Two, you can tell them that you really appreciate their interest but you are not ready to date or enter into any kind of relationship at the present time. I would recommend that you consider these options since you don't want to end up hurting either one of them and the longer the situation goes on, the greater the chance of doing just that.
