Should I take him back?

So I broke up with him because he wouldn’t “claim us” after 7 months. I got tired of waiting and doing everything as boyfriend and girlfriend but then he wouldn’t claim us. So we went separate ways he started “dating” someone immediately in like a month..me I’m still single..I casually hook up with a FWB every now and again..but now...my ex is back! He wants another chance..should I take him back and see where it ends up? Side note: we were great together but had a lot of petty arguments..he’s an Aries and I’m a Leo. We could rarely agree on certain things and he was always competitive when at certain times I needed that sensitive..emotional bonding. That was a deal breaker..What y’all think..should we go for a second time?
