Have you had more than one steady partner?  

Talking about one serious partner, I only have one at a time. But dating?... well I think is common and ordinary to date different man. Well one time in my life, while in a relationship I also date another man maybe because I like this another man. It is a bit hard because you are thinking that your partner might caught you anytime, sometimes you have to turn off your cellphones, sometimes you have to learn the time management, and most of the time you have to choose a dating place which is far from what you and your partner usually go to meet. But in the end I realized that I am just being stupid, because my partner is so loyal to me and he loves me so much... he can forgive all my mistakes. So I kissed dating goodbye and stick to my partner instead.

Hi happy.. i have never been in that situation. I don't think it's fair to the other person. If i fall in love with another while in a relationship, it only means i am not anymore in love with my boyfriend. And before jumping into another one, i would usually give my partner so many chances before breaking up with him.
