Re: I don't feel the same about my husband.
I dealt with something similar when I was first married to my now Ex. He used to travel for work about 75% of the year as a consultant. I traveled with him when I could as the assignements were long and often in other countries, but I could not always go. I really struggled with the balance of wanting a normal life and how to deal with him gone all the time....You establish a routine set your life up for this person to be gone and all is going fine and then they show up and disrupt everything and then leave again...Lather, rinse, repeat. I began to dread the short spurts that he would be home, and resented him for being gone and the limitations it put on me/us. Our solution was for him to find a job with very limited travel and we stayed married for another 20 years. Had he stayed with his consultant job our marriage would have ended after 2 or 3 years.
In your situation I don't know what I would do, you not feeling the same about him is obviously not a good sign. I went into therapy alone when I was going through it and my shrink told me most marriages don't survive these sort of situations (not a stunning bit of info there). Do you even want him to get a non travel job at this point?
