Josh and Kristen..... Everyone has offered really great insight into their relationship. Ten years of marriage sees a lot of change. I couldn't even legally drink (nor could my husband) when we were married and we celebrated our tenth anniversary last month. Have things changed since we were first married? Hell yes! Was it/is it hard to cope with those changes? Hell yea! It's how you deal with them that matters.
We have a one year old and a four year old. I worked full time until the one year old was born so the oldest was in day care and we had to arrange our schedules accordingly to pick him up from school. That was nice, for the most part, we had dinner as a family everynight. Then, one day, after several discussions, my husband decided to open his own blue collar business. Found out baby #2 was on the way shortly after. Once I had him we decided together I should quit my job due to day care expenses.
Being a SAHM was hard as shit, at first, especially to two kids all at once! I expected DH home for dinner, bedtime routine, bath time. He wouldn't call or text and many a fight occurred between us. One day we both just kind of snapped at each other and had a major discussion. In the end we both made some compromises and I never expect him home before 7:30 and usually one weekend a month where he works. The kids have gotten used to it as have I. He's usually on a job site where shit goes longer than expected and the way he works, it's easier not to have to bother with notifying me, unless he's going to be HOURS late!
All this to say that yea, Josh is a dick in how he demeans his wife. And Kristen could get a lot further if she picked her battles more wisely. Part of what I was dealing with in regards to DH was that I came from a working background and think I resented the fact that he actually got to leave the house and work where I never got a break from the kids. He resented me in a way because I got to stay home and have fun. You've got to flip the situation and think of life in the spouses shoes to fully understand that each of you have faults but each of you work hard in your own way to provide for the family and move on. I think they both just resent each other too much to have any empathy for the other.
