K.C.
A week huh? Well let me say this before every other wife and probably husband says it first. That's pretty darn good! I've been married to my husband for 9 years and living with him for 11 years and just like any other relationship there are ups and downs not to mention extremely dry seasons of sex! Especially with kids involved.
I can definitely see though how this, combined with his general lack of interest in other areas and financial concerns would upset you. Know this for a fact....money issues can affect EVERY aspect of your marital and family relationships. Money problems are one of the top reasons for divorce and I know from experience it takes quite a bit of work to get through that and keep remembering that this too shall pass.
When I'm feeling disconnected from my husband I pick a time and a way to broach the subject with him when we aren't arguing. I often do this in the car. If he's driving and doesn't have to make eye contact with you or physically engage he's much more likely to really discuss the heart of the matter. I also put it in simple terms. He doesn't need nor want to hear every single detail of how I'm feeling, those conversations are for my girlfriends. Men just aren't that way and that's not how your going to get things to change. Ever watch post-game shows....just the highlights right?
Make "I" statements. Not YOU don't do enough, YOU aren't spending time with me, YOU aren't interested in sex, YOU go to bed too early. Those won't work. Try I miss you, I miss our intimacy, I love spending time with you and was hoping we could set aside one hour a night to just hang out, I am also concerned about our financial situation but I feel like we'll get through this like we get through everthing else. Do you have any suggestions you'd like to try to alleviate our financial constraints? I could really use some help around the house, are there any chores you would feel comfortable enough taking on? Make sense? Don't pit him against you, bring everything to the table as a team. Your a family and in order for your family to work everyone needs to work together.
If he doesn't respond to this then you need to make it clear, again in a non-confrontational way, that he needs to step up here and tell you what's going on and what if anything you can do to help. Men don't talk, period. They internalize most things and work it all out in their head and then figure it out or obsess over it. He could be tired, stressed, depressed or all of the above. By arguing, crying, ranting, etc you add to that and that makes it even harder to push through it or have him open up to you.
Remember, your in it together and if he can feel that your here to help and make things work instead of adding further stress to him I am certain he will come around and work with you to change things.
As for the cockiness....I don't deal with that well at all so I'm not sure I have the best suggestions there. If you can, simply ignore it. I tend to come back with snarky comments and I'm not sure that's the best way to handle it.
Good luck S.. As I tell my husband all the time. Ebb and flow.......everything has it's ups and downs and we'll get through this together like we always do!
