First, you are not being a complainer or having a pity party! You have very valid issues...many big [[[hugs]]]
Now- You didn't say what this fabulous job is? One that involves travel all over the world, staying in luxury hotels, ritzy dinners in exciting venues, partying with hip people,etc...yet pays too poorly for you to have household help? Huh? These are job perks or they part of his compensation/pay for his very demanding job? Which is it? Perks like that are awesome, but as pay...hello! That doesn't take care of your family, does it?
He's gone till late every evening and gone every weekend? If you are serving your country, that's a different story...it's a sacrifice that is very much respected. Even Uncle Sam has more respect for family life than your husband's boss does apparently.
Your husband thinks your home is chaos? Or Is he really missing romping with his toddler, chubby arms around his neck with I love you daddy whispered in his ear? Is he missing the precious weight of his newborn laying on his chest, smelling sweetly of lotion and warm momma's milk? Is he missing your head on his shoulder while you sleep and your loving arms around him cuddling? Video chats via the computer just aren't the same. In my point of view, there's NO job worth missing your children's babyhood for. Period. I am playing the devil's advocate here, but I smell a rat.
To me, this is a single man's job, not one for a married man. So....it's time to consider that maybe he loves that lifestyle much more than he does being a hubby and daddy, with more normal work hours, or he would be the one making changes.
I hate saying these plain things to you and perhaps causing your sweet and tired heart to hurt more, yet it needs to be said. You are an understanding and loving woman, a dedicated mommy, and very defensive of your absent husband. You might as well be single for all the family life and happiness you are enjoying. [hugs!] These should be some of the most wonderful years of your life and I wonder, if this continues, will the little time you have with your husband will be enough?
It's time to get some help. You must put your foot down and tell him to get home at a decent hour when he's home during the week, start asking for the weekends off during the weeks that he travels, and get you enough money for some help. You deserve that, you need it, and your children need a mom that is rested for safety's sake. Accidents happen when people are overtired and don't get breaks. You need some exercise time and time for your creative outlets. Do not be palmed off or be made to feel guilty with bologna stories about how his mother did it all alone. No matter what others have said, just because you don't have an outside job, being home alone and over burdened isn't some exciting priviledge. It's frustraing, or you wouldn't have needed to discuss it with the kind and wise moms here.
Take care! Be proactive and let your husband know what you and his kids need!
