Ex texted me last night to go for drinks?

My ex who dumped me texted me begging me to go to where he lives for drinks and I told him no and he said he wanted a chance for us to work I also said we’re done and over as I tried with him for ages and all I got was baby steps so I gave up.
He then started calling me names to then apologising saying he was upset and I asked him why and he said he was depressed. Baring on mind I’m depressed myself but he never would care and would hate me for it. And I asked him why is he depressed and he said I just am. And I said maybe you should stop drinking as he was drinking while he was talking to me. And he’s now ghosted me once again I’m done caring for this man because when I try and help it gets me nowhere only me upset. I just don’t get why he always has to bully me or text me we’ve been over a good few months now and it’s like why?
