I want to echo this and say that acceptance cannot be forced through intellectual logic. Anyone who believes that logic rules feelings is just disconnected from their feelings, and their intellectual "acceptance" is nothing but the denial of what they feel.

When someone has just been hurt and the pain is raw, what needs to be accepted and validated at the moment is the part that feels pain. Trying to rationalize the pain away is the opposite of acceptance. Once the pain is processed, then acceptance of the bigger reality can take place, but not before.
