Good Morning...I can't really post alot right now b/c I'm getting ready for work but I do want to suggest to try to figure out what it is that you want...
Do you want your M? Do you want things to end between you and H? Do you want OP? Regardless you need to get that point especially aside from what H decides to do. If you need time alone to figure things out that is good too. Dont react to his actions...do what you need to for you.
I will try to post later but this is what I think is most important.
