How should I handle a local temptation while in a long distance relationship?

Ok, so I have been going out with a girl for about 2 years now. It is a long distance relationship, not ridiculously long distance, we are about 70 miles apart. We typically can synchronize schedules a few times a month to see each other. I have been unflinchingly faithful to her. A new girl started at the place I work who is very attractive and flirty with me. She managed to get my phone number during a lunch break food ordering ordeal and had been occasionally texting me ever since somewhat flirtaciously, I tried to respond as dryly and plainly as I could. A few nights ago I was at a party and got outrageously drunk. I hadnt planned on this so I couldnt drive home. It was about 3am, she was getting off work and texted me. I needed a ride so I asked her and she agreed. Once back at my house she asked to use the bathroom. I let her come in. She came out completely naked and started kissing me on the neck. I think I may have enjoyed it a little but I did quickly tell her I couldn’t, and that I was too drunk for her to be around. I feel terrible about it, I’m afraid that she might come see me again because now she knows where I live, I don’t know what to do, should I tell my girlfriend?
