If he loves you that should be enough. :)
Just tell him that it wouldnt be the same without him there and that you love him and want to spend as much time with him as possible. Tell him that it would mean everything to you and if he loves you as much as I'm sure he does, he will go with you :)
Havee fun :) xx
Havee fun :) xx
Promise him a trick or treat of your own if he comes with you !
He should go trick or treating with the boyfriend because he is a nice person and if he loves you, he will do it for you.
Just ask him to be there for you and be your protector, if he really loves you for who you r than he will go just to keep you safe from those little strangers of his :) l,ol
