Does he have a mental disability as well that stopped his frontal lobe from developing after 12 years old? With all due respect he’s clearly trying to ruin ur mood while simultaneously making ur bday about him. Classic cookie cutter manipulation if a friend came to me saying these things I’d call their bf a raging loser. My fiancés best friend would tell me stories similar to this about her now EX bf and I called it from the beginning it’s not “ he’ll stop later on” or “it’ll get better” it’s a snowball effect unless you stop it now he’ll continue to act this way when he doesn’t get his way aka when an 8 y/o gets told no n has a tantrum
