Ok, going by the intensity of this ML's trust issues (...or, more like, his full-blown "paranoia"...) I'm starting to wonder if there's a chance he's acting like this because of the way his father treated his mother (as just a mistress, etc etc), I'm even trying to think about what kind of scenarios would make a guy grow up with THIS level of relationship insecurity: I don't dare think yet about the chance the ML became like this due to getting cheated on in some previous relationship (because, that would have to mean he has had another "serious" affair before, aside from his "thing" for the mc). However, hasn't the ML been caught up in his feelings for the mc *for ages* (specifically, since high school?). So, leaving the chance of a previous failed relationship aside, the only possibility that is left is that he's reacting like this because of the impact that his own parents' shaky relationship had on him.
Still, I can only imagine someone "projecting their parents' relationship" this bad onto their own relationship if it was a lot worse than just an infidelity: maybe because his dad took "infidelity" to another level, decieving his mom not just by having another woman, but by having a whole hidden double-life with an entire second family to match, "on the side" (wife and kids and all...)? Heck, maybe rhe only reason his mom got called "the mistress" was because he didn't put a ring on her finger too, like he did with the other lady (I mean, it's all thanks to the internet that nowadays no one can get away with being "legally" bigamous anymore, because, believe it or not, before the internet it wasn't that easy for people to get notified whenever "creatures" like those broke the law by secretly tying the "legal" knot with two different women, at the same time)
