25NL 6max QQ with KK on board???

[Fidodell]

Villian is 62/7/0.25 over 110 hands... Before this hand he's been calling me with anything... and same pattern was emerging.. I raise pre he calls... I CB he calls.. I bet turn he calls... I check river he bets I fold... guess what same pattern happened here... is it ok to call this on the river given the situation??
