F****** up my business

It sucks when you have a person you were supposed to be in a relationship with who every time you turn around destroys your connections. The Tool Man and I do not talk anymore because she came between us. My brother and I cannot be around each other because he is still in his feelings over her and now that she is on another page I cannot trust her around him. This is literally wrecking every business Connection that I set up so it is going to have to stop one way or the other
