not sure what i need to do

I love my hubby very much and driving was his dream..when he went to school for his cdl every victory he had was mine too.and when he had set backs it was my heart broken too.

After many years of tow trucks etc. He went out on the road when I got sick and couldn't work no more. He loves it and I'm glad he does and I miss him lots but don't tell him how much it hurts sometimes because i don't want him to feel bad.

We have had ups and downs over the last 8 years and well, lately he has been starting fights with me over small things. Yes I might say something and it makes him mad and then he will not talk to me for days.

It seems like when he is in a bad mood because if dispatch or other drivers it ends up I cant say or do nothing right to him.

We never get to really see each other but make the most of it when we do,but lately he has started lashing out on me...the littlest things that we did fuss about now ends with him saying something mean hanging up on and before we would work it out after a day or two.

Never nothing worth leaving over as all couples do, but since he is driving its hard to work it out on a phone. But I know he loves me and lately it turns ugly with him and he has changed.

He tells me he's tired of my shit and that its over and everything......we made up last time but he is doing it again. We me and the kids love him so much and I CANT SEEM TO UNDERSTAND why is he treating his biggest cheerleader like this?

I tell him how proud i am of him and tell everyone else that he is good to us. What am I doing wrong and why would he be lashing out like that now? This is something new and it scares me and the last thing i want to do is think that he is doing me wrong with someone else.

I just wanted to know if this is a stage that truckers go threw where they start pushing every one away at times and is there anything I can do to improve this? I believe in marriage and the bible so its hard not to stay and want to work all out.

But I need a truckers view on what i must want to consider doing or thinking that they have. My hubby is not an open book and is hard to read because he does bottle things up.

Not sure if its me or if its just to much for him.
