I think Tink is saying that by running away, Regina denied Robin the chance to know and love his soul mate. What Tink is missing is the rest of the story: Marian and Roland. Obviously, Robin isn’t going to say that his life was ruined at all. I think that may actually be something RegalHood is going to have to work out together: Regina’s life was ruined because she chose her hatred and fear, but by doing that Robin had a good life. Sounds like fun filled TV drama to me!
I don’t know if I agree. Robin does, indeed, have Roland, and Roland clearly makes him happy, but he lost his significant other, Roland’s mother, and has had to raise him without her. If he had, instead, met Regina and had fallen in love with her, he probably would not have had any kind of relationship with Marian, and he would have Regina. I think that that is what Tink means.
