Yes mainly. he sees her as a threat and may not accept her till the biggest part of hormones are dwindling which may be this coming winter. My Runners never even stopped mating at all this whole winter. But the hormones sure weren't are like they are now. So just keep letting them be around each other with you there to keep it under control and it will finally get resolved it just takes time. If he goes after you pin him down to the ground on his belly facing away from you hold onto his neck so he can't bite. Hold him like that till he stops trying to get up, then let him go with a shove. Your going to have to put a stop to his behavior towards you. Biting is unacceptable. He is hormonal but needs to know his limitations.
