Hello. I believe I can be of help to you with this issue.
You have considerable emotional power and financial strength in this relationship, probably more than you realize; I suggest this because you describe your husband as being somewhat childish (and, i would probably add
, self-focused, a bit narcissistic, emotionally immature). You FEEL he bullies you, tells you what to do, but I think one skill issue is, Do you acquiesce to his bullying, back down; give in to what he asks you to do, etc.? First step would be to stop doing this and assert your personal power in the relationship. Your husband will likely escalate his bullying, trying to regain control and power in the relationship, because your 'disobedience' signals to him that he hasn't acted strongly enough with you and so, he will try again. But if you are consistent in this, e.g., simply telling him 'no', and explaining that you insist on being an equal partner in the relationship----do this over and over again, he will adjust to it and you won't feel quite so controlled or bullied. The real, underlying issue however, is your fundamental problems with communication; you feel your husband doesn't' really listen to you and most importantly, can't empathize in any way with what you experience or feel. You can approach this problem in your conversation by suggesting that you BOTH follow one new rule when you talk about a problem, issue, conflict etc. That is, before either of you respond as you might wish to, each of you must explain what they think other person just said to them and what they believe the other person is thinking and feeling in the moment.
This rule would disrupt the normal, highly defensive and self-focused responses he is offering up to you when you talk. I suspect he won't want to do with with you or will try it, but immediately fall back into his old modality of conversing with you (because the old modality serves him so well). But you can persist with it if he does this e.g., "I simply won't converse with you as we have in the past about any conflicts, problems or issues; we have a communication problem in that we don't listen to one another and tend to immediately respond from our own needs or wants. Until we break this pattern, i don't feel I can communicate with you or work on problem whatsoever and so, unless we can both agree to try this, I have nothing to say to you as no problems or issues really get settled; so before you respond to me as you normally feel you want to, I need to hear that you understood what I said to you, and that you have a clear understanding of what I think and feel right at this moment." So you would try to coach him and persuade him to try this preliminary step in communicating, so as to disrupt what you've done up to this point point in your marriage.
The problem you face is that you don't need the skills you seek----but your husband has huge skills deficits, or he doesn't really care much about your relationship and your emotional needs in it (one of these two). For HIM to pick up the skills he needs, you are thus, faced with trying to persuade him to communicate with you differently (as for example, offered the one idea I suggested above), or find a marital coach or relationship coach who can work with both of you, teaching you this stuff in real time. I suspect this was the basis of the last expert's recommendation to you. NOW if your husband simply won't cooperate, or won't put any effort into changing the role he plays in your relationship, you may have to create an emotional crisis in the relationship by moving out for a time, or asking him to move out---a period of trial separation---to communicate to him that this is pretty much a do or die, deal breaker issue for your marriage, in your mind.
So this would be the first, fundamental skill for you to try to get him to cooperate with and try i.e., each of you talks, but then takes turns communicating to the other person what they THOUGHT they heard them say, and what they think the person is thinking and feeling in the here and now; then, they can proceed to respond as they normally would if they wish. If your husband won't even try this, won't cooperate in such an experiment for a few days or a week, then no other skills you possess will matter, because as I said, you don't need the skills, HE does, and your skills can't 'fix' him and his deficits, if he won't cooperate with you in improving your relationship. So he has to admit to the notion that the two of you have serious problems, and he has to be willing to try out some new forms of communication---he has to say to you, o.k., I'm willing to try to change a bit, if it will improve our relationship. I'm going to pause here and solicit your feedback. I may not be able to get back on line with you for a few hours or possibly, tomorrow a.m. early, ; but I will get back to you as soon as I can, o.k.?
