i do think in his own way phil does love shirley and her him as they accept each other for who they are, both good and bad, shirley also redeemed herself partially as a parent by being a good mother figure to ben even if did turn into a killer of her best mate hev
sharon will always have hatred for phil for dennis death so they wont be able to have a good relationship and her history with grant will also be a factor
phil needs to wake up the fact he cant be a bully all his life and if he wants a relationshop get rid of his bullying ways
i watch too much dr. phil
