How did you meet your longterm partner as a demi?

I been in therapy and been single for 1.5 year and my therapist said i should start dating , but i don't feel ready . She then described how people ( read heterosexual) meet and they found love and i should consider dating again. The way she described how people meet ( blind date , arrange marriage setup , co worker etc.) They made me lil uncomfortable, i just couldn't imagine myself meeting my future partner that way . Which made me curious how commited /married demi like me met their partner. Maybe that provide me guidance for myself.
