After all of this input from us pinball addicts (of which some are happily married, perhaps some unhappily married, some happily divorced, some just divorced, possibly some engaged, some happily living a girlfriend/boyfriend, some dating another but living separate, some getting it on w/ multiple partners, and others tending to steer clear of all of this type interaction),
and upon some time to reflect and consider a few things, just curious how you have decided to proceed w/ your situation.
You could do nothing and carry on as if no big deal.
If she was just having a bad moment, then perhaps all is well in Iamdarras's world.
If all is not well w/ your lady, and you blow it off, then whatever is bothering her may just fester inside her for a while til she boils over and pops her top.
At that point you will be faced w/ a similar situation.
Is it possible that something else is actually bothering her, and you need to really sit down w/ her and ask her what is bothering her. Does she want to get married and start having kids and you are dragging things out too slowly? Are you ignoring her to much and not making her feel special? No need to answer to us. Just wondering if you have thought about other possibilities.
Oh, and just to clarify further, If you ask her if it's ok if you just do pinball stuff all weekend and her answer is "Fine!" in a quick stern reply. Please note that in womanese talk, things are not fine.
More talk may be needed in the "expectations" category.
Ask her what would make her happy in 2013 concerning your relationship.
Er, um, maybe not a good idea. She may scare you off with her answer. Good luck.
