ADHD

I was just broken up with someone I was dating for 2.5 months. It is a short amount of time but I am devastated. I was blind-sided. He said he had trouble forming a deep connection with me. The ironic thing is everyone I know thinks this is insane, since I have a deep sense of self, am empathetic and easy to connect with and have several stable deep connections in my life with family and friends. He has ADHD and would forget things we talked about, would be inconsistent with plans and always was seeking a dopamine rush. My therapist just told me people with ADHD struggle to form connections with romantic partners because their brain is constantly jumping from place to place. It’s definitely possible that he just lost interest in me but I am wondering if anyone else had dealt with this.
