His ego/mind was bruised/injured (theoretically speaking) - knowing you didn't tell him makes him feel unworthy and "less than" in some way. He took on the "poor me" how could she not tell me, trust me, love me enough...etc, etc.

But, you have to remember he doesn't know your suffering like you do...he hasn't dealt with the on going knowledge of it recently, because as you know, you didn't tell him. He may be in a bit of shock that he didn't know you were feeling this way and has been probably going on with life as usual. He may even have guilty feelings that are uncomfortable and therefore turned them outwards towards you.

I'm sure he loves you and wants to help you...try to remember that others who are "quote on quote" ...normal... also, have difficulty with dealing with things appropriately at times.

I'm glad you told him...now try to keep the trust intact with being honest when you don't feel well. Keeping secrets is no way to live- But I get "it" I've done it myself in the past- but paid dearly for it also...

Just my 2 cents
Hope you feel better soon!
