Friendships,relationships,loss and getting over things.

I am hoping that some of you may be able to relate and help me out with this. I have unfortunately gone through alot of emotional upsets within the last several months. I lost a good friend due to very personal issues that we couldn't seem to see past. Very recently this person is back in my life and things are akward at best dispite effort on both our part. Is there anyway to make things less stiff and akward? I lost someone who was dearer to me than I can express...lost them in nearly every way it is possible to lose someone and dispite the fact that I have been deeply hurt by this person I cannot get get past the pain of the dissolution of our friendship and can't convince myself to just forget. HELP!!!!!

Act the way you always did and s/he'll follow suit. Duh.
