Over time I choose to spend more time with her, it turns into a relationship, I stop talking to others. Same for women. This is how dating works.
Since women are the ones approached, they already are picking from a line of suitors in general (compared to men) yet long term relationships are still forged. How?
It's like if you gave me three apples, and said "which one is the best," I'd be able to tell you pretty easily. If you gave me two thousand, the best one would probably be better, but I'd probably be very indecisive about which one was best, and probably be wondering even as I picked it whether perhaps another one was actually the best.
It's more like balancing spinning plates. You don't have the bandwidth to keep up more than a few, and you have a pretty good idea of which one is doing the best. Some of the plates drop off, or you stop them, or the other party does, and you can take on new ones as you please. Or you decide you're done looking. But that's exactly what you did. You settled after some samples.
But worrying about indecision because you have so many options is like worrying about exercise because you don't want to accidentally look like Arnold Schwarzenegger, or not wanting to apply to too many jobs because you don't want to have too many godlike offers to choose from; Having so many women to choose from that you're indecisive is not easy and it's a quality problem to have, but I don't think that's most men's realities despite their efforts.
