What am I doing wrong?

I recently got out of a long term. My ex & I were dating for four years until we broke up in September of last year, but officially parted ways in January after unsuccessfully trying to work things out. The breakup devastated me and I went through a traumatizing time. My ex put me through a lot and caused the relationship to end.

Back in July, I felt healed enough to start online dating. I’ve been on two dates but nothing happened out of it. I haven’t been intimate or physical with someone in almost a year. I have had zero luck with online dating. I’m putting myself out there, which is some thing out of my comfort zone. I’m honestly having a hard time finding someone. My ex has already moved on & has found people he’s interested in. And to be fair, he’s single he can do whatever he wants! However, online dating is so hard and I’m honestly not getting anywhere. I’m trying to find a long term relationship or someone I’m interested in but I’m having literally ZERO LUCK & I don’t know why. I’m trying, but receiving nothing out of it.

My ex has gone on dates, been physical with girls and I’m over here not having anything going on in my life. I’m not trying to compare my dating life with his but he’s such an awful person and he hurt me so much yet he’s thriving and living life and getting lucky. I know it sounds silly but I don’t understand why It’s taking me so long to find a great guy.

My ex still tries to pursue me all which entertain multiple women, which I find trifling. I did not take him back due to the lies, cheating, betrayal and emotional

trauma he put me through. We talked a couple weeks ago, which is how I know how his dating has been going & funnily enough, he failed to give me time, love and affection during the time where we were trying to work things out but yet as soon as we part ways he jumps from female to female, and give them his time willingly.
