What can you do with online dating now that you saw a guy lying about being single and moved on to someone else to make sure the new guy is single?

I also lied to one guy who did lie about being single. I did find out he did have a girlfriend through a social media site called Snapchat, and I blocked him after I found out he had a girlfriend. The girlfriend did hack into his Snapchat and start spamming chat. I will also block users if they aren't single. I knew he wasn't single, so I wouldn't have to wait, but I did move on to someone new, and I made sure the new guy was single for real this time. I was also lied to by some other guys. Did you get that the fake nice guys acted to get someone in return? I have also been lied to by some girls as well. I don't have many girls as friends since I had bad experiences throughout college when I did get a lot of attention from guys and had a few relationships, but they ended. Some of them did cheat. Some girls did use my trust to get close to guys with whom I had a relationship in college, and some girls tried to tempt guys to cheat and were successful. I stop dating and having relationships in college and start finding them outside of college. I had two more relationships, but both of them ended. We did not end up together because another guy had more than one girlfriend at the time. The other one ended because the guy did not change into a good person. Now I have nine ex-boyfriends.
