My husband has lied, had affairs, slept with prostitutes

I think I am in shock. I discovered 10 days ago that my husband of two & a half years, a man I have been with for nearly 8 years has lived a completely secret duplicit life away from me. He admitted to an affair with his secretary a year ago after I discovered love you & miss you texts he’d left on the computer. I left. I’ve been staying with my parents & have just been contacted by the best man from our wedding, who hasn’t been in touch at all since the wedding. He told me that James was having affairs before we married, had slept with whores & took vast quantities of cocaine. I had spent the first 4 years of our relationship nurturing him through a divorce from his 1st wife, it was particually aggressive & I ended up having to sell my flat in london, & remortgage our cottage to finance the split. I didn’t see the money, it was nearly £150,000 & I’m now told James spent the majority of it enjoying his stinking, seedy obsessions. James has always professed to adore me, I have moved back to London for him, left my family & friends & my job. I now know that quite a few people knew what he had been up to & he controlled them not telling me by saying I was pregnant & would miscarry if I was told. He doesn’t know I’ve been told everything & is still contacting me professing regret, sorrow, remorse & saying everything I want to hear but it is ALL lies. I can’t believe a man that I loved so much could do this to me. It feels like my life for the last 7 years has been manipulated & controllby a complete fantasist & narcissus, & psychopath really. He is 6’5 ex rugby player & quite arrogant & aggressive, he is v intimidating but has never raised a hand to me, more emotial abuse & bullying really. But I am worried to let him know I know, I think he will come out fighting if his house of cards come down. I’m v worried about what my financial rights are, being a second wife with no children. I just don’t know what to do. My Father is a Doctor & my Mother a barrister & they are dumbfounded by this, they loved him & believed him too. It is all so abhorrent, I don’t know what to do…
