I adopted many "alpha" behaviors. I don't seek validation anymore and I am dominant among other things.

I've noticed things fizzle out quickly with me and other girls. I know it's not because of neediness or seeking validation. I'm thinking maybe it is also because I don't contact them unless it's for a date. This can lead to periods up to a week or more where I don't talk to them.

Why do things end so quickly for me? Any help appreciated.
