You can call on Marquis Amon for reconciliation. There’s a mega thread about him here. You can also call on him to break them up as well. He can bring people together or break them up.
If you want to work with an angel, work with Haniel, she’s helped me in areas of love.
He could have done that for a variety of reasons. I would focus more on softening his heart, breaking him away from the woman, and reconciling with you.
I thought my situation was a lost cause because my target is also being manipulated by a woman he’s barely known because she’s insecure over our friendship. That relationship is causing him to be cold and distant towards me and our child. He was a doting, loving dad that saw his son all the time. He got with her and threw our 2 decades worth of friendship away. I took a long break from trying to break them up & out of nowhere he contacted me and broke down, told me how he felt and went on and on and on. Sad part is he is still with this person because he needs a place to stay so i’m back at square one. I’m stuck with him forever through our child so I refuse to give up.
So I’m speaking from experience when I’m giving this advice. I know how frustrating it can be.
