URGENT RELATIONSHIP ADVICE NEEDED

Emily

So my partner and I live together (have been for about 3 months and have been dating in and off since December 2017) and this morning he said to me “I don’t think this is going to work” he said “you have 2 days to prove that this can work, it’s on you, you need to be more committed” and I asked him “what can I do better? , how can I make this work?” And he said “if you don’t already know the answer then you shouldn’t be here”

A lot of the time he complains that I don’t clean or cook and that I’m lazy (he works full time I don’t have a job)

So basically wondering what can I do in the 2 days to prove to him that it will work out, I really really love him and he says he loves me too. I want to make it work because I don’t want to loose him
