How to deal with your husband traveling for work?

My husband and I just bought a house in April and since moving in, he’s been gone almost every other week (the longest he’s been home is 2 weeks in May). He’s just returned from a 2-week trip, only to inform me that he has a 4-week trip in July. I keep asking myself how I seemed to manage better before this but I think it’s because I always thought there was an end in sight. That and if something major happened in our old apartment we had maintenance to fix it, whereas now I am in this new house, in a brand new city without him. We were putting off having kids until we bought a home. But now that I am here and I realize how much I am struggling alone, I can’t imagine adding small humans to take care of to the mix and this is causing some grief as well (we both want kids). I am seeking therapy (first session this week!) because I already struggle with anxiety/depression and the frequent unpredictable travel kind of exacerbates it. We’ve been having a lot of discussions about the travel and while he hates being away, he doesn’t think there are any better career options for him (and I know he loves the job and has put a lot of time and effort into it) so I should suck it up and find more things to fill my time (which I do: family visits/overnights, I work full time, I catch up with friends, find new recipes to try, and I listen to so many audiobooks, also while maintaining the day to day household stuff) — but none of those things help when things break (like our HVAC) or with the extreme nighttime anxiety I have. While he’s gone, we do make an effort to keep in contact often and I am always excited for him to return but lately, I’ve been feeling a lot of resentment towards him even when he’s here, and obviously, that’s causing some tension between us. When he’s home for such a short period of time, he’s still working a lot but also has to make time to see friends and family because he’s gone so often (which I logically know is a good thing but sometimes when he’s still so busy and home these things add a little salt to my wound). I am starting to feel more like an accessory to his life and it’s like we get started on things, get into a routine, and then he goes away — so I have to change things up and put things on hold and I start a different routine and then he returns and we do the same cycle all over again. I feel like my life just stops and starts and I don’t want to feel this way so I’m hoping therapy can help me cope better because I want this to work but I’m struggling. Any advice?
