Lets assume one thing in this hipothetical sitaution: im not dropping my career just so she get fired 5 years afterwards and we end up broke. If we assume that she takes care of money forever, then the answer is yes.
I dont want kids, so that wouldnt be even a question. Id rather break up than ahve kids forced on me.
As far as doing the chores and cooking - i already do all that living alone so while the demand would increase for two obviuosly but i cenrtainly can handle. and i would probably have more time for new recipes too which is cool.
And yes, i would definatelly have more time for games that way.
I dont get bored at home. in fact the only times i leave the house is when i need to. those involve: work, shopping, visiting family/friends.
Last summer on holiday i havent left the house for whole week, same goes for when im sick. Im not afraid of outside or anything, heck every summer i go on a camping trip with friends where we go "no technology for a week" type of deal. but im perfectly confortable being at home all the time. Actually i usually plan my outside stuff in a way that i would ahve to leave house as little times as possible since "thats just wasting time". Which is why i always thought id be great for those space travel to mars experiments. i can see myself sitting in same house for 6 months easy.
