The fuck did I just read? You asked for an open relationship because you got “bored” but now all of a sudden HE cheated? You need to go look up the definition of an open relationship apparently. And now because he’s happy that he doesn’t have to deal with your dumbass shit anymore, you all of a sudden want him back? show up at his place, WONDER why the new gf doesn’t like you, decide to get hostile at THEIR place so she does what any smart person would do and mace you and file a restraining order. And she’s the psychopath? I do not feel bad for you one bit, you brought all this on yourself without help from anyone else. This is a literal interpretation of wanting your cake and eating it too. Get your shit together. Continue with therapy, my god.
