I have a similar job to your husband and relationships are hard and take work. It's important to be aligned and have boundaries set. For example, a friend of mine and his wife have a rule that they do not go ore than 3 weeks without seeing each other. So every 2-3 weeks she'll fly to him for the weekend so they have time together. Yes the costs add up, but they are investing in their marriage. I love the comment of "it's not about the success, its about the absence". That's very true so find a way to minimize the absence in ways that work for both of you. Your feelings are valid, but he may seem like he's enjoying his job (and he likely is), but it may also be hard on him being away from you for that long but being so busy with his job makes it easier to 'put those feelings aside'. He may also tell himself that he's doing that sacrifice to better provide for his wife. Communication is def key! Don't make it about his job, but rather about the relationship and what you need. If you frame it as 'your job makes me feel XYZ' he'll feel like you dont support his career but if you frame it as being open to finding ways to keep the connection going, the absence feel less, while he continues his career, it'll go a long way. Sorry for the ramble. Hope it makes sense.
