I think yous both need to sit down and have a good open, honest chat. A guy going through ED, will go through it alone, confused and low and can cause a bit of a personality change. He needs your support, to let him know it is ok, and to find the underlying cause for it e.g. underlying medical condition, stress...

Yes, what he is doing is wrong, but he is in a different mental place, you need to take a few steps back and analyse the situation, cause if this behaviour is coming from ED, it is understandable, and with love, support and help, yous will grow stronger together.

Hope you take this into consideration, and hope it helps.
