You know, i have been following this thread since the start. And i found it somewhat shocking that most people take dating someone so lightly as to date multiple people at the same time and have the dillema of "choosing" which one to take.
Have we lost all ability to work at building relationships?
Have we lost all tolerance for others who are not the perfect fit?
Is there no more effort to be put into the other person?
Guess what. Relationships are meant to take time and a lot of work for 2 people to mesh properly, it's a time for growing personally and spiritually, relationships make you wiser in a way that simple dating around does not.
I find the practice of dating multiple persons to be just wrong and immoral and i am surprised at some peoples reactions of taking it so lightly, when the fact is that you are doing yourself a huge disservice.
I would never date a girl like that. It happened once, and when i heard the "i want to date a lot of guys" talk, i left. I never came back. Saw her years later while at a club with my GF of 4 years and she was still the same, looking all stoned and ravaged by partying not to mention the extra hefty weight on her. But hey she is dating a lot of guys.
People are not like pets, you will not find the perfect one with the perfect manners, so stop looking for instant gratification and WORK at building YOUR perfect relationship you'll be glad you did.
