“i understand how this all sounds but you need to understand he is truly a good person.”

Being a good person doesn’t equal being a good partner. There are a lot of “good” people in the world who are bad partners, parents, coworkers, etc. We all have to expend effort in relationships and meet each other at a place of compromise. For you and most people his excessive gaming and time spent otherwise occupied is a deal breaker.

It’s okay to leave simply because you’re not getting what you need.
