Clever move Glenn. Very cunning. That is, if he doesn't get desolved, That worm might just bring him to the nest before the others arrive.
Am I geting some trust issue vibes from Glenn? "Woman get bored quickly."? I don't wanna go down the "He just didn't meet the right girl. He's so dreamy"-rabbit hole here, especially as he threats women just like sex toys and trophies, but maybe all women got bored of him, when the bad boy thing was through, they wanted more (a rich princesses lifestyle for example) and he couldn't/didn't want to deliver. "They don't like the real me." (Well, that would really kind of suck, but still: Mind your manners!) And at some point he disposed them, before they reached that point, sadly also getting rid of any girl that might have been "not getting bored" aferall. That and the thing, that his first few days romance didn't have any troubles making friends and he got really depressed on the spot. (No instant soulmate for you, buddy.) Must have hurt.
Yepp, yet still an unsympathic fuckup for being an arsehole. He should go and redeem himself by marrying mage girl, even if you only started to "date" her because of his unresolved 1-minute crush.
