You've gotten some really good advice here - and I'm sure that you two will be able to work this out.
Speaking of working things out, I've found that when issues flare up like this, one of the best ways to be able to talk about stuff is to go on a walk together. Sometimes, these issues become tense and difficult to talk about, and if you're out walking together - it is surprisingly easier to get through these kinds of conversations. I suspect this because you get the feeling of being 'grounded' (feet on the ground) which means you're not all in your own head, feeling like your emotions are swallowing you up, and further - the very act of walking means you are literally moving forward. In a weird way, this can help your mind and heart move forward too - and it also helps "move the conversation forward" instead of getting stuck on the same, sticky points. I'm just talking about a simple walk around the neighbourhood, not a major hike or anything. I highly recommend trying this out. In fact, I'd recommend a daily pre or post-dinner walk most evenings for a little while. The issues may or may not come up at first, but eventually they will - and they won't feel as tense when you're out walking together. This might be all the counseling you need
The other thing I wanted to mention is that my husband loves to take me along on almost all of his business trips, and during these - he wants me to attend the evening socials/business dinners. I've felt kind of pleased and flattered, but I also don't necessarily find these gatherings enjoyable all the time. Sometimes they are boring, and so on. I finally realized something though. You see, my husband is an introvert, and I am an extrovert. After a long day of being "on" while on a business trip, having to then go out for dinner with a pile of work people is even more of an effort than usual for him. With me there, I am able to chat with people about non-business stuff and lighten things up a wee bit. Don't get me wrong, he's very good with people, but he *is* an introvert, even though most people would never know this about him. I've since realized that having me along for these dinners helps reduce the pressure on him, and relieves the sense of exhaustion that introverts sometimes experience when spending all day and all evening with a pile of people.
The reason I mention this is because there's a chance that your husband finds it comforting and helpful having you there with him during some of these activities. This is actually really good news - he loves your company, he's proud of you, and likely there's some other aspect to him asking you to be there - maybe he's an introvert? I mean, you can't always tell. And even leaving aside the possible introvert/extrovert thing - perhaps it's just that having you with him makes him feel better about himself, makes him happier and so on.
Another thing I noticed about my husband's introversion vs. my extroversion? It's not that he wants to be by himself at all, it's just that he doesn't always want to talk non-stop. Sitting in the living room, each of us reading our books quietly is a wonderful thing for us to do together. Just because he's more introverted than I am doesn't mean he wants to be alone. There have been times when we've been apart, and he does *not* enjoy this at all. I think if I talked non-stop and expected him to be 'on' all the time, he'd prefer to have some alone time. But this isn't the case because I've recognized that he has a need for peace (and quiet). It's wonderful to enjoy each other's company and still have that peace.
Meanwhile, I will also say that he makes a real effort to spend time just 'yakking' with me every single day. He literally plunks himself into a comfy chair and says, "So, what do you want to talk about?" He does this even when he'd rather just have some peace & quiet.
Somehow we manage to make it work most of the time. I like to talk and socialize and he appreciates his quiet and downtime. You wouldn't think it would work, but it does - just that we both need to recognize these things about each other and do a bit of give and take. Sometimes I forget and bombard him with talking, and sometimes he forgets and goes into quiet mode. Nobody's perfect We're able to laugh about it though, so I think this helps.
You and your husband will be able to balance all of this out, I'm sure of it.
