I have been on and off MN for years but needed some impartial advice as I have no one to talk to, so I decided to come back 
My husband and I are at odds right now, we have been together for 15 years and married almost 10 of those.
We never argue, we bicker very occasionally but generally just get on with it. The last few months DH has had a lot of problems at work and is very unhappy there. I am looking for work now that our youngest is starting school full time this September. I have been looking for work, anything and everything, since the new year and had just one interview 
I know that DH is frustrated that I seem unable to find any kind of work. He doesn't say but I can tell.
He wants to leave his job and is currently looking for alternative work also.
He seems to be picking fights with me, having sly digs at me and generally being awful towards me.
We had words yesterday but the kids were there so I left it as I did not want to have words/argue etc in front of them.
Since then he has been the model DH kind, attentive and actually nice to me which makes a huge change from the last few months. I however cannot seem to pull myself out of this 'funk' I have gotten into since yesterday. I can't appreciate his efforts, I actually think I don't want to appreciate them. I don't want to be around him, spend time with him or even talk to him. I do normally get like this, as childish as it is (I know), but after a couple if hours and maybe a trip to the gym and I've gotten over it. I can't seem to this time.
I really am sick of him blaming me for everything, and for having digs at me and bickering with me. We used to talk things out I am unable to talk to him now as anything I say is, in his own words, my fault.
I know he hates his job, I know he is not happy there, I am doing everything I know to find work. I'm taking two late night courses to get an IT and Maths qualification to make me more employable. I have registered with several job agencies and have applied for so many jobs I have lost count. Not just specific jobs but anything from cleaning and fast food to factory, retail and office. Literally anything
DH seems to think that I should be able to walk into a job tomorrow 
I am avoiding him, right now I could happily take the DDs and walk away from him.
I think I have changed so much that I can no longer overlook the way he is with me.
I need a bit of advice, I have no one to talk to, no friends, my family are just awful and I have finally started to get them out if my life. I get on really well with MIL but I don't want to talk to her about her son like that its not fair on her.
The friends I do have live away and are having a tough time with things themselves. 
Apologies for spelling and grammar mistakes I am on my phone!
