Am I a bad lover if I play around?

Here is the deal:

I am the kind of guy who will fall for a girl hard, but last year I had maybe 3/4 casual lovers. Now I am getting close to 30 I want a life partner. There are a number of girls who fit the bill, but each has complications that make it hard for me to fall into the swing of things.

Am I a bad lover for making connections with 4 girls, all of whom could be that special person, but not being able to make the final decision?

I love them all, and know they're all into me - what do I do? How can you make a final decision when you have a history of 'playing around' or the knowledge that there's always someting else out there?
