I messaged my married ex, "Let me know you haven't fallen into a sink hole and wish me a happy birthday." He didn't respond. My ridiculous obsession. I had a crazy booty call on again/off again relationship with him for ten years. I was crazy about him, he was just crazy. I lost touch with him for 20 years. We reconnected and emailed for a year. Nothing came of it. I left him alone for two years. Now I messaged him because I never stop thinking about him. He never wished me a happy birthday ever. I figured what the hell, hearing from him, even to just respond with an obligatory birthday greeting, would make my day. Can you say Relationship OCD??? Ugh! Kinda hate myself.
