I am sorry you’re going through this, but I really think you need to make the steps to change your lifestyle because it seems you jumped from one bad situation to the next.
It also doesn’t sound like your marriage to this man is a ‘valid’ one in the sense that you say you never loved him… the right intentions for marrying him were not there and so it shouldn’t be too difficult for a priest to understand what you’re going through and what you are in this marriage.
Do talk to a priest. Most of them are very good at giving you advise and pointing you in the right direction. It’s either that, or you’ll have to continue living in a miserable marriage, an unhappy lifestyle, and who wants that?
Keep us posted.
