Hey Cindy, I know you are having a rough time. Been there done that but not near as long as the time you guys spend time apart. It takes a special relationship that can be in long distance ones. My hubby is 2 weeks in and 2 weeks out. It is hard on everyone. In the beginning it was hard for me but since I was always independent I learned to be resourceful. However, even in my husband's company, they do a background of your family life and if it is unstable you may not get hired.
It has been 10 years now and I do go through times and wonder what if. But what YOU have to decide is, will you be able to live your life without him? As my motto is , the grass is only greener over the septic tank! Hang in there, tell him how you feel, you both are a very nice couple, hate to see that doubted. Hugs, hope you hang in there!
