Gs. does dating make u nuts and why..?

When I was a teenager up until I got married I had no problem except the usual painful break up. Even casual sx was no problem. After my divorce same thing. Then I got sick of dating and stopped. Last yr I started and it makes me nuts. I have this all or nothing thing and I either like them immediately and want to sleep w them or I can't be bothered. And casual makes me crazy too. So I've. Stopped altogether because it's a bad example for the kids. But u think it's cuz of my past failure that I'm like this.? It's like I can't even have a burger w a Guy.?
