What Did I Do To You Today?

Hubby is constantly complaining that we don't spend enough time together. Saturday I had to work an 11 hr shift, and then work 5-1 sunday. When I got home sunday, we had 2-3 hrs to ourselves, I thought great we have some time together. I came in from work, after recieving a text from him earlier in the day, saying I love you and I know your tired. Apon entering the house, he was on his way out to take our granddaughter to a friends house. When he got home he did nothing but complaine about how our days off don't coinside with each other, and he always has kids on his days off. I said to him, we have a few hrs together, he could of cared less. Treated me liike the plague, wouldn't talk to me, told me to get out of his space, and that I needed to clean house better, pretty much said, your worthless. As tired as I was I walked away and started cleaning. Seriously, why do I bother? We've been together 25 yrs. I have put up with some major crap from this man, and usually most cases, I just ignore him and walk away til his attitude changes. I do love him, and have spent half our yrs together knowing or feeling like he hates me. Why do I stay, I swore the day I got married, 1 marriage, and if we divorce, training another man, not worth it for me. I would rather spend the rest of my life by myself, not having to answer to noone.
