There is not much you can do. The I-485 was denied because the marriage is not bona fide, which it is not if you are not living together as husband and wife and he is not supportive of the process and has another person. So, you have no basis for the I-485. Your options are to leave the US, get divorced and get remarried and refile with a new spouse.
