What's it like when DH works away from home?

[FrizzyFrazzled]

I'm just looking for a bit of feedback really - my DH has been struggling in his profession for a long while, and now things are really happening for him and he is becoming very successful. I am thrilled for him. He will be away from home for a week at a time, sometimes more. We have a 1-year-old DS. I have no problem with him being away because he is about to get his dream come true, and things at home are pretty easy - I work freelance from home and have a supportive family etc to look after DS if needs be.
However, I am feeling a bit nervous about the change in our relationship really. My DH works weekend evenings mostly, so we spend a lot of time together, he is my best friend and I just can't imagine being without him every day. Since we moved in together in 2005 we have only spent the odd night here and there apart, two nights is the longest. I am just after some advice/stories of how relationships change when this happens I guess. I have weird worries like we won't be able to argue because I wont want him to go away when things are tense, or that it will be hard not sharing the mundane, daily things with him...
Anyone have any experience of this to reassure me?? (Or warn me!!)

DH and I spent the first two years of our relationship long distance, so I understand what you're about to be dealing with. Phones are such a powerful tool, if you and DH are as devoted as you sound I'm sure you'll enjoy talking about what happened every night. Make sure you both get Skype and other tools so you can have good conversations. Sounds like he won't be gone too frequently and this is probably just a stage in his career, it doesn't have to be permanent. Maybe you can find ways for you and DS to visit him a couple days during his trips depending on where he's going? I've heard of that being done.

Thanks braidedsilver :). We have got Skype installed!
In the future, I can probably accompany him on shorter trips before DS starts pre-school. As long as I have my laptop, I can work so that's lucky.
How did you find it when you were actually together? How did you manage when you got lonely and really, really wanted a hug or a chat or something?
I guess I know it's just going to be a big change, and a bit scary really. Want to be prepared!
