Just a depressed post

It really sucks. Me and my husband have been married for almost 12 years. Have a 2 yr old son and 7 yr old daughter... and #3 (a little sister) due in a few weeks. Anyway, our relationship has been rocky for the last few years... About two weeks ago everything just stopped and it got better. Not sure why. He started actually coming home after work at night to actually spend some time with us before bed time, played with the kids more, wanted to take the kids places, got home early enough to spend some time with me and our personal life was getting better. There was joking and playing around and his old personality coming back. It looked like the clouds were finally breaking up and life was getting better again as a family... Now today he is going to be ‘late’ again from work when I know he is out with his friends instead. Now this would be fine, except its not when you lie about where you are and are going out and having fun behind my back while I spend all day fighting with kids, cleaning, contractions and endless paperwork and phone calls (we are finalizing purchase on a house.) If he wants to go out once or twice a week, I don’t care, but he is right back to lying about where he is and leaving me, yet again, to raise the kids by myself just like he was before...
