Thank you for all the advice!

I started school and enjoy it very much. My husband has been home with the kids and even gets home a little early. I have made sure that they have dinners at night so that he has to do as little work as possible.
I have been so frustrated by the fact that when I come home the house is a mess, the dishes aren't done, etc. Everything that he complained about, and that he was going to do differently on his own is not being done, so hopefully he is realizing it isn't as easy as it seems.
He was acting very cold towards me and I called him out on it. I wasn't mean, I just asked why, and he said he didn't know what I was talking about, and he has been different since then.
He is still sleeping on the couch and I often ask myself how long I am willing to live like roommates. He gets to go where ever he wants on the weekends, he gets to hang out with friends, while I am at home taking care of the kids. I don't know how much longer I am willing to do this. I love him and I want this to work, but I am changing and he isn't. I am trying to be patient and remember that my kids deserve to have their parents together and happy, but I am not happy right now. Do I keep giving my everything with nothing in return? Do I keep fighting when I am the only one in the ring with gloves on?
This is the hardest thing that I have ever done, it so lonely and so exhausting.
I have been reading about mid life crisis and even learned about the different stages in life in school. I am positive this is what my husband is experiencing. Everything he said and has done to me is a classic, "bored of life", going out with the guys all the time, not spending time with kids, not doing things as a family, wanting to buy a new car. The only thing he isn't doing is hanging out at the gym. There was one event in October and from that moment on he wasn't the same. I just hope that things move forward, because with my new life I am finding for myself, I might just realize that I am worth more than I think.
