Coincidence or me exaggerating

Soo me and my husband recently started a job together and there was this girl that was too flirty with him so I told him not to talk to her and he still did so he got mad so things escalated quickly and I slapped him. ( I know stupid me) and he said that was it and ever since nothing has been the same he left me even though we ate still married we are still living together but he says he wants to separate and that we can do whatever we want and he doesn’t want to do literally anything anymore and so he changed his password on his phone and today he bought a screen protector the ones where you can’t see the screen and there’s this girl at work idk if its a coincide dont or what but I literally see them beside eachother ALL the time and I’m like what!? But her bf is my husbands friend. I DO NOT KNOW WHAT TO DO!? am i going crazy or is that what I get for slapping him ?
