They will sort things out in time. It's important just to supervise them whenever they're together to catch things early if they start to get out of hand. If one is going out of their way to bully the other, that's when you might need to step in. A squirt bottle might be helpful. If he starts getting too rough with her, squirt him and use a command such as "Settle." I use the term with my pack when they're getting overly excited about something, barking, etc. just getting carried away with whatever. Generally speaking though, they will work out their relationship eventually; just a matter of them figuring out the others' boundaries. =) Good luck!
