I need advice on a difficult situation i am going through.

I am \[25 F \] and I’m in a relationship with a man \[36 M \] . We have been together since 6 years now. Things were great when we got in touch initially, but in a few weeks after going through his Facebook profile, I got to know that he is already married. I decided to leave immediately but when I confronted him, he told me that he has separated from his wife around 8 months ago and are not on good terms. He convinced me hard to stay by assuring that he would be getting a divorce very soon. I believed him and decided to give it a shot considering our compatibility and bonding.

We have had fights now and then but we have stayed through it all. Time passed and years have gone by and he always kept telling me that his financial situation is not stable and if he filed for a divorce he would have to spend a lot of money on lawyers and possible alimony, which he couldn’t afford. I have always been patient with him and tried my best into not pressurising him. But sometimes i feel uncertain about where this is going, i have asked him to do something about it so that our future can be secured. But whenever i bring the topic, he gets very angry and dismisses my concern saying that i purposely bring it purposely to spoil his mood.
He has never let me check his phone and makes a scene out of it when I have asked him for it. However, I have let him check my phone when he insisted. He even gets verbally abusive when i express my concerns in general- when i nag about wanting more time, ask him to put more efforts, ask him to get a divorce etc. I try my best to not bring up such topics that bother him, but I am a person who likes to plan my life wherever possible.

It’s going to be seven years in this December. He has not started with any legal proceedings. He says he can’t start initiate the divorce untill and unless his wife files it, otherwise he will have to face consequences. He tells me that if i really want to marry him I could just run away with him without telling my family. In his religion, marrying more than once is accepted, but I am strictly against it. When I tell him that, he tells me that I am making excuses. This is a major concern I have which keeps bothering me now and then. Bringing this up again will again lead to a major fight and I end up promising him I won’t bring it up again, just so that he won’t get upset.

Please let me know your take on this and would be the best thing for me to do.
