I don't know anymore...
I never dated anyone until about 7 years ago. I had a few of those very serious gut-wrenching & emotional up-and-down relationships since. Then after the last serious one (2 years ago) I just kind shut off emotionally - although that progressed slowly.
I began doing everything I could to feel happy and content, structure my life so that I wouldn't miss anyone not being in it - i.e. every night, I would:
1. go to the gym after work
2. then take a hot lavendar salt bath (relaxing + good for you internally)
3. alternate at-home "spa" treatments (mani-pedi one night, facial the next)
4. watch shows that either made me laugh or realize I never dated anyone as attractive as a vampire (True Blood!)
5. focus on attaining my perfect body, being in a perfect state of health, and totally content.
I kept doing that, and then when I tried to date someone new, I felt bored and suffocated...I couldn't spend a weekend with him without missing my baths, gym time, eating my own healthy food, watching my shows alone in peace (with my cat), etc. We broke up (finally), and it was like he never existed. And the same thing recently with someone I dated for 6 months (6 months passed between him and the initial "new" guy).
Everything seems predictable now...I've met too many people that want to date someone just because they can't stand being alone. And me becoming a vain selfish loner has made me say "no" to being someone's shrink-with-benefits.
