You're right to worry. He's a class A tosser in my opinion. Personally we left him in Waukeens promenade and I take great delight in sticking a couple of arrows into him every time I return there. Shoot him, talk to him, shoot him more......great fun
I don't know if Shadow keeper is an option open to you although you may be just as well to look on it as if it were a real life adventure and you just messed up with her. I had Jaheira and I thought she was pretty good, but there are others out there to take her place.
Oh, welcome aboard btw.
