I am not the one trolling on this topic, you are. I haven't trolled anything in awhile.
For real, I'm not sure what his issue is. You admitted you were wrong and apoligized yet he still won't help you AND he has been insulting you. It's insane. Must have missed the Sesame Street on forgiveness as a kid.
Is there any move in particular that's getting the best of you? Like his chain grab, shield charge, or golden fleece? Otherwise all I can offer is generic advice.
Personally I rely on blocking more than dodging (not that I stop dodging entirely) with Kratos, his moves come out so quickly that by the time my dodge ends he's already starting on another combo, it's much safer to block until there's an opening and retaliate. Unlike most characters, Kratos has few ways to start combos from the air, but at the same time has very strong air moves that make jumping around dangerous, for the most part he's going to be grounded as he's trying to combo you, so use Ratchet's awesome grab whenever the chance arises.
Sorry if I'm telling you what you already know, any additional information on your situation could help with crafting theories on how to react.
