I’m not sure if you have bio kids with this person but I would recommend taking them and starting over new. This guy sounds like scum

He's a  big, fat failure. For whatever reason, he doesn't have what it takes to hold up his end of a healthy, successful relationship. He failed before you, he failed with you, and he'll continue to fail at coupling unless/until he learns his lessons and evolves.

Move forward from this mess of a man. Don't be collateral damage in his life. Grow, live, experience, and love beyond his particular step nightmare. Don't be defined by his shortcomings.

Are you saying that he routinely files for divorce and then rescinds it? If so, that's incredibly emotionally abusive.  Good for you for making it stick this time.  Block him and don't look back.

He's broken you down to the point where you think you can't survive on your own, but you can.  Friends and family may help temporarily, or even domestic violence groups, since he's clearly been emotionally abusive to you.

Good luck. You will not only survive but thrive without this nonsense. This has nothing to do with being a stepparent, it's about him being a controlling, abusive jerk.

But worthed it in the end.  Atlesast you don’t have to play mind game anymore 

Hang in there, you can do this.

Have you talked to a lawyer? You quit your job, at his request, to help with his business. You should not walk away with nothing.

Take care of you. Enjoy setting off on your new life adventure.

Never again sacrifice yourself on the alter of Sparental Martyrdom.  No relationship can thrive if the partners put anything above each other and the relationship.

Kids need to be kept in their place.

A lesson no doubt you have learned well.

Good luck. 

Enjoy!

The ol' "Im gonna divorce you if you don't shape up" game is not love, it's a power trip game.  He loves control more than he loves you and is willing to sacrifice you to his ego.  My first husband played this game our entire 13 yr marriage with several children involved.  It was abusive to me and them since the fights were always in front of them.  Like you, I finally said yes, he filed then desperately begged for me to come back.  Once I was free of his threats I couldn't disrespect myself and live that lie again.  It was over.  He has since went on to marry a few more times and I can only imagine he's played the same game.  

Get out and stay gone! Be free OP.  

making divorce threats like that over and over is abusive behavior.  you need to see it for what it is.  it comes under withholding affection, which is abusive. 

your h is the one who had you served hoping you'd beg him not to leave.  he will get exactly what he asked for.  dont reply to his texts and go what they call no contact.  your h may have a mental disorder.  he is abusive and plays games. 

my own h did this for years and it upset me until i found out it was his bluff to divorce me.  when hed threaten i would laugh at at him and tell him to serve me.  in more than twenty years he has not had me served.  now the divorce threats no longer happen.  if they do i am ready.  and i will laugh at him again.  i know my legal rights.
