Playing mind games with each other. F(22) and M(30). And he said let’s change it. Should i give another shot?

I (22F) got into relationship with men(30M) for 8 months. After being in relationship, i found out that he has this toxic personality (narcissistic traits not sure fully narcissistic) and it was effecting me. But i did stand up for myself and noticed i also have some traits of it as well. We had great times as putting effort for each other traveling here and there. I wouldn’t say he is bad man. But at some point we really played mind games with each other and trigger each other’s insecurities. Middle of the relationship, i noticed dude hiding his phone here and there. And found out that he was texting to multiple girls at some point i was the same ( last relationships) to seeking validation and just getting attention or just somebody to talk to. So anyways, dude got revealed as his bumble profile and we broke up. But after since dude had hard times and needed to face with himself that what he scare of, he was ass full of ego shit and stuff. So now he coming and begging back to me to let’s go back together, start fresh over. For me, i met pretty many people as guys to talk and understand and it is really rare to find this kind of connection and understanding level to each other. It is really good deal for both of us that what we can provide each other. At some point i do know better to ignore him and move on. But just deep down have some hope that holding me on. It is 50/50 and like brain and heart fighting with each other. What should i dooo?

Tl;dr: now started doing things that when i asking him to do while in relationship. And he acts way more mature than before. Or i am just gaslighting myself to go back? He do make favor to me that make my life easier and fun than normal. Or maybe i am the one (toxic) also using him?
