Wondering, for the first time, if this is where I am 
Been married for 14 years. DD12 and DS10. We've had ups and downs, but until now, the ups far, far outweigh the downs. He's been grumpy, but never EA.
Recently - last few months - he is permanently grump and withdrawn. Snappy with me and DC. Shouts a lot. Lots of silence. No interest in anything except TV. Resents helping at home. For the first time, I'm aware that I'm trying to anticipate his behaviour / reactions and modify mine accordingly. I am not prepared for this to continue.
Last couple of years have been hard - I gave up work for 2 years to try and manage the house, DCs etc (long commute meant we were both out of the house for 12 hours). This crippled us financially and we have lots of debt. I'm back at work (and back to long commute) and we're managing the debt sensibly. I'm not happy. DCs are not happy.
He's not having an affair. I do still love him and am sure he loves me. Sex hasn't been great since DC but we always had lots of physical contact, affection etc. Almost gone now. I'm lonely, unhappy and the environment isn't one I am prepared to tolerate for me, much less our DC. Desperate to find a way out of this.
