If you are good friends with her, friends should be honest. If you are not good friends with her, try putting it it to her lightly if not start by saying you saw something that seemed suspicious. Better to know the truth right away, then to feel left out and hurt by all that knew about it.
Because I would want someone to tell me if it was me.
Through past experience i have learned to mind my own business,as no matter what you decide to do your going to be at fault,
If we are good friends I would find a way to get it to you because life as we know it the innocent are always the last to know,and I would want someone to tell me,with tact and class not be ignorant with it and that will give me the option to stay in this situation or to handle it however I deem necessary...that is my story and I'm sticking to it...
To protect her from obtaining STD's or HIV...then to represent her in court.....ha ha...kidding! ♥Nassy
Because I am an honest person and could not stand to see someone else go through what I went through. Thus agreeing with Celtic girl.
I would also tell. Why should a woman waste her good looks being with someone who doesn't love, care or respect her. Let her know early on while she still has some looks about herself so that she can find someone who will genuinely love, adore and be faithful to her. Also, I would certainly want someone to tell me if my partner was cheating. If they knew about it and didn't tell me they would be cut off.
