Two years waiting for the man I love

I have been dating a married man for over 2 years. We are in love, we are happy together, we have serious conversations about our future together. Our connection is once in a lifetime.... soulmates. His wife finally filed for divorce a week before Christmas & he was served with divorce papers. He spent Christmas with my family and it was perfect. My family accepted him and could tell how happy we are together. His family blackmailed him to go and stay with his 81 year old mother because they don't want him with me....even though he told them the truth... that he is in love with me.... that I make him happy. He was strong for a week, but finally his Mom, sister, & brother harassing and blackmailing him.... he caved and went to stay with his mother. He told me he wouldn't be able to talk for a few days. Then a week later he tells me his divorce is on hold....that he agreed to go to individual counseling.... to try and save his relationship with his Mom, sister, brother, grown adult children/ grandkids. My heart is broken. His wife knew he lied to her not once but twice about me. They went to marriage counselling and it failed. He is not in love with her and will never be happy. Why can't his family be happy for us and accept that he is in love with me and happy? Why should he agree to live a miserable life and a lie just to keep a relationship with his family that claim to love him... but can't support what really makes him happy... me. I am so devastated.
