What still compels you to answer his calls? I get why he's calling--he's having big feelings and doesn't know how to self-soothe. In the past, he's relied on abuse, road rage, and venting to you. He may not want to show that side of himself to OW. You say you "caved", but what were you feeling that made you answer?

What were you feeling that made you keep listening? If my ex-wife called at 4am I might answer to see if her house burned down, but I'd be extricating myself soon after.

That sounds disrespectful--a good opportunity to hang-up.

It sounds like you're realizing what you two share is not a friendship. I suspect your interactions (puppy care, venting) would not be at a balance point even if he cleaned the gutters? My ex-GF had someone who regularly vented to her, but the venter always provided nice meals and drinks in exchange.
