Can my ex come back after losing feelings?

Did anyone have an ex who broke up w you because they lost feelings but after a while started to fall in love again? Especially if you're a woman and your ex is a man... cuz men's brain is weird ig lmao
I wanna know if its possible. My ex said "Nothing is impossible but rn I don't think we'll have a future" so I'm hoping but I know I shouldn't bc its very clear he doesn't want me back
