Uh no it's a problem that he bought and laid at your feet, with his cheating, you didn't pull this "trigger" problem out of thin air.
Explain when he tells you he will be hanging out with his friends your fears, because these are the same excuses he used when he was cheating, you didn't have triggers then because he gave you no reason not to trust him, since that trust is broken and calling you and telling you the same plans that he used for his cheating brings you back to that place again.
If he gets mads then he still does not get what he did to you and your son, and his behavior really has not changed (imo)
