How do you deal with husband/wife being unsupportive?

I'm a 41 year-old woman, married with one son and two stepsons.  My weight has been up and down for my whole life.  I just recommited to CC and healthy habits after tipping the scale at 201.  That's 15 pounds up from where I've been hovering since having my baby in 2005.  What happened is that I had a back injury, stopped teaching dance classes, broke my toe, and never got back on the exercise horse.  So anyway, now I have recommited, and today I took a 10-mile walk for 3.25 hours.  Yay me!  But the bummer is that my husband is totally unsupportive of me taking that much time to myself when he's home.  Of course, I can only take that time when he's home because I could never take my son on a 10-mile excursion!  Three miles, yes, but that would be the limit.  Plus pushing the 40 pounds of him + stroller limits my endurance. 

Any suggestions for how to deal with hubby's resistance to me taking this time for myself?  He's not an a-hole, by the way.  Just likes me around :-) 

My hubby likes me around too so I understand!!!  I am a stay at home mom so I exercise while my hubby is at work.  My suggestion is to forgo the 10 mile walk for the 3 mile walk.  You are still getting exercise maybe not as much but you are still getting it, plus pushing the stroller with the 40 lb. baby is burning extra calories.  You could also ask hubby to come along and bring the baby as well that way it is a family activity.  If he is anything like mine he will decline but still you offered.  Let your hubby know how much this lifestyle change means to you and that you both will reap the benefits of it in the long run.  If that doesn't work Marriage is the ultimate compromise and I think it will work better if you have a happy hubby and you are still getting your exercise.  By the way I think it is awesome that you are getting back in the game, and I think that once your hubby sees the results he will be more cooperative of your exercise.  Good Luck!!!
