Sometimes growing up is more like stepping away from people who can't deal with the important people in your life.

Whatever has happened between them, for a "friend" of yours to not approve of Owl who is supportive and loving towards you is kind of just not right.

I really understand wanting to hope against hope that you can keep being friends with this person.

But if he can't accept Owl who you want as a big part of your life, how can he accept you?

Maybe that sounds harsh, but I would honestly let go of him. Owl is good for you. People who make ultimatums on your friendship are not.
