What do I do? How do I move on?

She (23F) "Aiko" and I "Wendy" (22F) were friends who fell in love. After being together for a long time, 11 months ago I proposed to her. She said yes. We were fiancées. Well, she started spending less and less time with me, talked about her future with men and having biological kids which I simply couldn't do or be (a man and a biological father).

I ended up getting depressed in the relationship so I broke up with her. Aiko blocked me on everything and I tried waving to her when I saw her around the neighborhood. She just looked away and acted as if she did not know me.

I get she was hurt but I normally am used to the person agreeing and wanting to be my friend. What do I do about this? Do I cut contact permanently? Wait for her to be ready? What are your thoughts or experiences?
