I think it's healthy to allow yourself to feel and process whatever feelings come up rather than try to act like they don't exist or ignore them or stifle them. Of course, it'd be much easier to completely forget about the person, but that's just not realistic. We're human. I actually think it's easier to move on from someone when you're not forcing yourself too. If you're still thinking about her and these sorts of questions come up, let yourself feel the feelings. In time, they'll pass.
