You’re telling things out of order. You continued to harass him and message him from multiple numbers, you lied to him and said you had a therapist, and he reached out to him bc you made him and he wanted to make peace with you. The therapist said he didn’t even know you!
He shouldn’t have said that and he didn’t mean it. He was trying to get you off his back at that point. And I saw that you agreed to a Friends with benefits relationship bc you desperately wanted him back.
