Help a girl out

Right so basically me and my ex fiancé broke up 2 months since, we have a son together. And he said I've basically pushed him too far away because I have the worst paranoia in the world which I'm currently having therapy for. My ex came round tonight we had sex and he basically said and his words 'I don't think it will ever happen between us again, I dont see me falling in love with you again' on that note I obviously was so very emotional. One things tho I can't shake this feeling of still having 'hope' like I literally still have faith that we'll be together. He doesn't see himself together with anyone in the foreseeable future, he doesn't want any more kids nor get married. He also is still paying me my bills every month that comes to £800. We've literally only spoken today for the first time in a month. Please girls I can't shake this feeling it's like someone is grabbing me and telling me 'do not give the fuck up' I'm a strong believer in if it's meant to be it will be. Please tell me why I still have this hope because I've never had it with any of my other ex's😂 no nasty comments please! TIA xx

EDIT- He did say last night that he never said he'd never want to try again just right now he doesn't see it.
