I have a sorta similar situation. Life really catches on, the stress as well. We started having less and less sex, and I decieded even though my libido is lower than ever (mostly because of birth control) I decided to not let that get in between our relationship. So this week I initiated more than ever, turned the TV off, and decided to spend whatever time I have left with him. Before this change we had sex 2-4 times/week, since last wend we have had sex 12 times...probably another 2 tonight.
I just stopped making excuses, when you start having sex a lot you realize how much of an affect it has on your relaitonship and your MOOD. I am 75% less crank/moody since I started having lots of sex. Not only that but it's so healthy for the both of you (if your man ejaculates at least 5 times a week, his chances of prostate cancer decreased by over 50%, and it reduced your chance of ovarian cancer as well, especially if you don't have kids; thinking about all the benefits makes me crave it more).
I feel so much closer and so much secure when we have sex on regular basis, I know this last week was crazy but I am going to try and keep it, of course some weeks are just insane, but I try to make conscious effort.
I also started trying all this new stuff in bed for my man, not only is he loving it, he is doing some new things for me as well
