Have any of you gotten to the point of dating?

My therapist encouraged me (if I’m comfortable) to download a dating app and just see what’s out there-even if I don’t go on a date (it’s been a little over a month of a discard after a 2.5 year relationship with my fiancé who proposed to me while manic then slept with a girl 2 days after the discard). I matched with a guy and talked with him over FaceTime and it felt…bad. I feel confident in myself and have accepted my situation and forgive my ex. I feel comfortable being alone so I would not be dating out of codependency or loneliness). However, the idea of dating or sleeping with anyone feels bad. I feel like I loved so hard with my ex that anyone else feels like a downgrade. Maybe I’ll be single forever? (I’m 29F)

I have goals and dreams. But love? Anyone have dating experience after discard?
