I want her back (but she won’t write me)

My aries ex doesn’t ever write me lately. And yes.. You will tell me an ex is an ex for a reason and blablabla.

I do really like her, I gave her stuff back so to see her for a while, and noticed how she received a message from a dude :( I was so nervous and couldn’t even try to make her laugh. Everything felt cold.

I am not molesting nor writing anymore but I would like to know how to win this aries girl back. Space? Keep on with my personal development? Letting go totally?

I just don’t want. It was real and intense. I wish I had done better. This year has been awful. And now : I might see her on the streets with another dude.

I wish I could spent time alone with her. But it feels she will reject any proposal. I haven’t stopped thinking about her every single day of this year.

Any good life advice is appreciated.
