Is he a player???

One of my young colleges came to office crying today,and could not start work. We all were worried a bout her. By mid day I asked her what happened, and as I expected, she answered it is my boyfriend he has been playing with my feelings and dating other girls too! So I felt sad for her, deep in me I was saying *welcome to real world*!!
Later her boyfriend appeared .so I called him aside and asked him, *why have you been playing with her feelings, she loves you so much, we were getting ready for your wedding party*?
So he answered, some one else played with me before too and hurt me badly…!!
Now I face a tough decision as to whether or not to put up a wall. Do I want to get hurt again? I feel like I'm always the nice guy and getting hurt. So should I continue to risk opening up to these girls just to be burned again? How and when will I know a girl is serious? Maybe now that I'm afraid to get wounded I will run from commitment.

Now what comes along with the fear of commitment? The fear of finding the right person. How do I know I found her? I thought the first girl was the one. Wrong. I thought the second girl could have been the one. Wrong again. So how do I know?

There is only one thing I can do now. I will date different girls and see which one is the right one for me. I will let the girls know that I am only dating at the moment. That means if I meet a girl I think I might be attracted to I will ask for her number. Yes, I am dating other girls, but I am dating. I am not playing. It is there choice to stay in the situation or not. If a girl leaves and I think she was worth keeping I may have to make a tough choice.

Now I choose to tell the girls I am only dating. Other guys may choose not to say that.
So guys what do you think? Who is right and who is mistaken??
