Balancing obligations to one's significant other and the need to pass the exams is hard, so I sympathize. Before my first exam, my boyfriend's grandpa (who we're both quite close to – we lived with his grandparents at the time) went into the hospital in really bad shape – doctors told us that he only had a 5% chance to make it through the night. After he was released from the hospital, he needed lots of care and help, and we all wanted to spend time with him since we'd almost lost him…but I also had an exam coming up in about a month. The day before my second exam, my boyfriend's stepdad was flown to the hospital a couple hours away…so, my boyfriend kinda needed my support with his stepdad in the hospital, but I had an exam the next day! Through studying for my last 2 exams, my boyfriend had some major medical problems come up…and again, he needed me, but the exams needed me too!
So, I haven't dealt with the layoff situation specifically, but I have dealt with family and/or significant other obligations in the midst of testing. I've cried because I felt like I should be focusing on his health, but he encouraged me to finish the exams and worry about his health later (his problems weren't things that needed attention and care or that I could really help, just that made his life miserable and I wanted to alleviate some of the mental/emotional side).
But I think that the 2nd part of that last sentence is really the key to any advice I could give – what's his thoughts? My man pushed me to finish the exams, because I'd wanted to do this and he wanted to see me get it done. So, even though my instinct was to drop everything and focus on him, his preference was that I keep at it, so I could do what I logically knew was best and be doing what he wanted at the same time. Your marriage and your family are 100000x more important than these exams. If he sees his sudden freedom from work as something that allows him to help take care of the kiddos and the house for a couple weeks so that you can focus on your last exam, that's awesome, and you can get this done…and by Feb 23 you can put your focus back to your home and husband like you'd like to. But, if he is depressed about being laid off and really needs your support and attention right now, don't neglect that just for the exams. Talk it out and figure out what you both most deeply think, feel, and believe, and then figure out how to proceed from there. If you have to delay your exam till early April, presuming your NTS is still good, that's just a $35 fee or something like that – your husband's happiness is worth $35! But if he's supportive of you testing 2/22 and you're the one second-guessing, then try to not think about the layoff and just kick this test's a$$.
