Advice on what to do

Without the back story:

Hi everyone my partner has told me to move out even sent me a link to property website to find a place. We have a 18 month old and he said that baby is staying honestly I can’t financially take care of me and a child I’m still at uni and have a waiters job so it’s tough.

My partner also said that he is not allowing baby to come with me. I just need advice is there anything I can do? Or do I have no choice but to leave my son? I’ll leave uni and try get a better job but now it’s even harder as of COVID. It breaks my heart to think I’ll have to leave my baby after so much we been together non stop he’s my whole life. I live abroad so no family around to help out too. TIA
