Even if you're a cheater, bro, there are times when the particular situation forces you to pass it up. You gotta look into these things a little before you make your decision. How well do you know this girl? Do you know her friends? You may think she'll keep quiet but trust me, there's always at least 1 person she's gonna talk to about it. Now u gotta hope u can trust that person too. I see 2 problems with this right now. 1: Ur girl is already suspicious, I would let that wear off a little first. 2: Your girl and the bartender have at least one mutual friend that you know of. That can def. be a problem. What's the bartender's situation? Is she in a relationship? It works out so much better if she has something to lose also. If she's only keeping quiet for you, she probably won't be quiet long. I'm not saying don't do it bro, but don't jump right in to it. Feel out the situation a little. Good luck.
