maybe you should just wait it out and see how you feel in a little while. i know that waiting is the hardest thing to do but its worth a try. if you really like this guy for alot more than a friend the great, but if you feel like your feelings for women are to strong then end it b/c its not fair to drag him along...and depending on how well you know him and what his attitude is then you may or may not want to tell him he might take it the wrong way that his g/f digs other chicks more than she does him..idk but whatever your dessision be sure to take his feelings into perspective. hope i helped...if you ever want to talk feel free to send me a msg. :) good luck

Do you want to stay with him? I think sometimes you have to be honest, and tell him that these feelings were in your past. Do they make you feel like straying from him? It's pretty important to let him know either way. If you're serious about him, you want to be truthful, and if you feel you want to explore then you should tell him so he can move on. Honesty is the most important thing in a relationship, so it's best to keep things open! Otherwise, things have an unpleasant way of surfacing...
Lots of love, and if you need to talk, message me!

if you want to stay with him you could tell him your bi.. if not just tell him you are a lesbian.
