I'm sorry to hear about your situation, manny. This sounds very much like emotional abuse to me. Ignoring you, alienating your family, pursuing his own interests with no thought for you, being emotionally distant, making you feel you're walking on eggshells. No one should have to live like this. You deserve better. Your husband wants everything on his terms. How selfish of him.
I was married for not long short of 30 years; I was my husband's second wife - he'd been divorced for a couple of years when we met. Things seemed fine for a number of years - although looking back, there were signs that at the time I didn't really notice - but when he retired and I was still in full-time work he started really going off the rails. I divorced him 2 years ago - reason: adultery. However, his general behaviour was very much like you describe. I'm in my early 60s now. The thought of being left on my own in my late 50s frightened me at first, but I can now say I have no regrets. He was very uncooperative during the divorce, which took about 9 months when it could have taken just a few. But life on one's own isn't bad at all. I'd advise you to get good legal advice in the first instance and get your family on your side. I don't know your financial situation. I'm fortunate in that I have my own occupational pension and some additional income, and I negotiated a very good settlement which meant I was able to buy my new home outright. I suspect my ex-husband only agreed to that because he had other plans (i.e. to marry the woman he met a year after I'd agreed to move as he wanted 'a fresh start', persuade her to sell the home she owned and buy a new one with him in a different area, meaning he'd probably be entitled to half - so far, everything I thought he'd do, he's done).
I hope everything goes well for you. Let us know how you get on. You'll get good advice and support here.
