Hi Butterfly76,

The first thing that comes to mind is whether you are relying only on his words or you actually saw some proofs of his accident and his memory loss, like a medical diagnosis for example.
If you want the answers to your questions, I suppose that would be a good thing to find that woman and talk to her as well. Did you read the e-mails they shared?

However, I suppose you are wondering whether you should forgive him for what he has done and whether you can trust him once again and allow him back in your life. I understand he looks genuinely sorry and displeased. However, that’s not the man you used to know. He changed and warped back to some previous past, was he reliable back then? Do you think there were situations that could be avoided or do you think that things were going to happen anyway? If you try to rewrite the history from that point he is back at, do you think you may have success?
Anyway, amnesia may be only temporary, memories may come back and change his perception of the world. So he may change once again, for some reason you currently do not know. He is not reliable, unless you can count on some commitment from him: that whatever he remembers, he won’t let it influence your relationship with you, and will try hard to actually “forget” that it happened at all. If you want to give a chance, tell him that he should forgive you for everything, you ever said or did and he does not remember, that he should give up any other commitment he does not recall. If you can agree on that, maybe it can be fine to be back together. Tough you never know what may happen with a damaged brain, nevertheless, you would never know if something would happen even if he was healthy: he may have another car incident and start behaving strange anyway. Maybe you’d like to have the doctor’s advices on the matter, to see what’s the chance that old memories may interfere with the new life. If you don’t feel like you can take the risk, it is better to keep investigating or waiting that memories come back. Did he start any therapy?
