Nasty situation to be in. I would suggest talking to him in a friendly way and just outlining everything you said here. If he's not a dick, he should be happy to award you some equity. It's not fair to have 50% but you should get something.

Getting a lawyer involved immediately really escalates the situation and can make things quite hostile. I would only suggest it as a last resort.

Thanks, I agree that lawyers can quickly escalate the situation. His email to me was already pretty hostile, but I am trying to keep it cool unless there is no alternative.
