He got offended?

Agreed! I am concerned about his anger.

Tabenda,

There is a general issue of a double standard, understood broadly, lurking here as well.

The term "a double standard" is usually employed in situations in which, say, one partner has had many sexual relationships in the past but is upset that the other partner also has had many sexual relationships in the past.

The term can be used more broadly to mean any kind of a double standard, when one partner allows him/herself ABC, but is upset when the other partner engages in ABC as well.

The danger here is that ten years down the line, if you settle down with him, you would be expected to do all the housework and he, none; add any kind of unfairness between two partners you can imagine and that would be the risk.

What I am trying to say is that you are right in being concerned about his anger, but there are other risks, concerns, and potential for trouble here.

I absolutely agree here.... his reaction was unreasonable to me and not something that I will ignore or look past.

I agree that I think there's something else that was bothering him. I feel like I am still missing what it is that angered him. I do plan on talking to him about it once a little more time has passed.

I think letting him cool off and approaching him in an non-inflammatory way is a great idea. And then his reaction will be your data for decision-making.
