I'm very lost and at my wits end?

I'm really struggling and it's getting worse by the day. It's been over a year and half since my ex cheated and dumped me for someone else. In that time she has moved in with the guy. I have been trying to date after I took some time but I haven't had a second date in this whole time. The majority of these women I had no interest in and they still rejected me. I've moved and started a new job. I've gotten to the point where I question life every day. I'm very lost and need help?
