<human>: Recently, my ex split up with me. We had been going out ~4 years.

The relationship wasn't perfect but we definitely loved each other and had a lot of good times.

All of a sudden, she breaks up with me saying that she just wanted to be alone, and that the love had faded (even though, days before, she was confessing her love and making plans about our future). 

I know she cares for me (or cared), but now she doesn't want any contact at all until she says so.

How do I deal with this? I still love her. I'm not clinging to some fantasy, or scared of being alone, **I genuinely love her with all of my heart**. Am I stupid for thinking there is hope? She said there isn't any, but she has a history of being over the top and irrational.

I really want to get back with her, but I don't want to be sitting around waiting for her if there is never going to be a chance we could be together again. I don't want to jeopardise what little chance there is that we could be friends.

I'm trying to let go for her sake, but it's hard letting go of these feelings.

Can you condense the text into three sentences or less?
<bot>: We were very close. Our relationship had problems, but the breakup was sudden and now she doesn't want to talk at all until she says so. She just wants to be alone and doesn't want to get back together.
