So I've been in a LTR for about 7 years now, and all throughout I've been hit on AGGRESSIVELY by other women. Out of respect for my gf I never followed through with any of them, but I was real close a couple of times. I never really had a serious issue with it until the other day when an ex coworker of mine came on to me and asked me out. This one was different because of how attractive she is. All the other girls were hot, but this girl is on another level. So I went out with her and we talked for a while, I didn't really care what she had to say and I didn't really find her all that interesting, I was just going through the motions trying to see where it would go. Long story short, I have the opportunity to sleep with her nsa but I'm a little scared that if we do it then it could get out and back to my gf since she works in my area and we both have friends there and they could talk. No one there directly knows my gf but I'm still cautious. To make it worse, she told her friend about us and her friend has seen my gf but she doesn't know she's my gf. Basically I asking, should I still go through with this and if so, any suggestions on how to handle this situation so that it all works out in my favor. Ultimate goal is the sleep with this chick and still stay with my gf.
