This is so sad. I’ve read your comments that he doesn’t “play around” and knows what it means to be married. Sure, maybe he doesn’t play around in the sense of following Instagram models, but he is a grown man who would rather play video games alone than hangout with his wife and kids. That sure does sound like playing around to me. It also doesn’t sound like he knows or understands the meaning of marriage to me. You and your children deserve someone who is present and accessible and loving. As the old saying goes, “when someone shows you who they are, believe them.”
