I can't offer any advice. But Cubby is the same way with out growling and running. He hates my husband for no reason. He is always giving my husband dirty looks when ever he is curled up next to me or when he walks past Cubby. Cubby likes to be left alone but when he wants to cuddle with me he wont let hubby get in his way. The whole time he lays on me if you look at the way he looks at hubby it's funny. It's almost a look like 'I got her and you don't so ha ha ha!'
