I need advice please 😪

So I meet this guy in April 2016 we were together for 2 months then he moved to Missouri for job corps. After he moved here made another Facebook pages he blocked me from his main page and put me on the page he doesn't use that often. So I got suspicious and started to lurk found out that he was cheating on me with a girl from there. So we broke up and they were together for a month and then he broke it off when I found out about them. He want me back but Idk if I should go with him what should I do???
