Sex addiction/ OF/ hookers

Heyy, so my hubby and I have an active sex life@ like a few times every 10 or so days. Anyway, just found out hes been paying for cam girls/ only fans, been to a strip club and has used 2 hookers?! (I presume it may be more), he has an addiction (confirmed), i want to support him, but I dont want to stick around, we have a nearly 18m old baby to!! Sooo upset, feel betrayed, angry, all of the emotions. Just wanting some advice on how to leave but still.be supportive.
