Advice please

Can somebody please give me some advice? My husband and I have been together since 2015. We have 2 little boys. We've been through a lot and got through everything. He has cheated on me in the past, which caused me to have insecurities and trust issues. Last night I heard the TikTok trend ",,have you seen my silhouette," play on his phone. So I asked him what he was watching. It was literally a guy working out🤦🏻‍♀️ so I accused him of something he wasn't even doing.. he has now decided he no longer wants to be with me. But literally just a couple weeks ago he didn't wanna be with me because I " didn't listen" to him and hit the unlock button on the car. But I thought that it automatically unlocked when we got next to it. It's a fairly newer car. Am I wrong for wanting him to stay? Should I try go get him to? And if so, how? He is the love of my life. Or do I just let him go?
