OP - deep breath. Take a break. Yes, it's normal. It takes longer for some people than for others. I've been at this for a year and a half (after being single for 5 years following a divorce)... nothing has lasted longer than two months. I got really frustrated earlier this year and took a break from "trying" for a while. It helped me a lot. The other thing that is useful for me is trying to learn something about myself from each person I date - whether it's one date or 10, it helps me figure out what I'm looking for, what I could have done differently, better ways to recognize and handle new situations, how to identify (and not ignore!) red flags, etc
