walked in on him

I don't think there is anything wrong with him getting his rocks on with himself like this -- unless he's a recovering porn addict and this violates his healing, or, porn goes against y'all's marital boundaries and he's exploiting your ill downtime to sneak a little something something on the side. Just because you are ill and miserable doesn't mean that he has to be miserable, too. Getting angry about this seems like an overreaction. Apologize sincerely and then just leave him alone until he is ready to accept the apology and get along again.

Of course, if you are seriously ill (& this isn't just a virus or something) and he is your caretaker and being negligent at your expense, then, make some time to talk to him about your needs and feelings, honestly and openly. Otherwise, take a step back and look at the bigger picture because you are BOTH individuals with needs and not servants of each other bound solely to a function of marriage that has become routine or expected. If it's the porn itself that bugs you, wait till you're both past this little storm and then discuss it rationally.

How long did he neglect you? Obviously you were upset for a specific reason but Im assuming he spent a lot of time away or took too long to get you something requesting due to him trying to get his rocks off? If you were sleep or just minding your business while he was doing this, whats the deal then? Sounds like you are looking for something to be mad about this is the icing on the cake. I understand if you're sick and he's suppose to be by your side making sure your needs are met. I personally don't like to be bothered too much when Im sick. I like being pampered by the W but other than I prefer to just keep to myself because Im so irritable when Im sick. Think you need to be more specific to him as far as either being mad at the act of him doing, him doing it to porn, or it consuming time that he could have been taking care of you.
