What should I do? Please help i'm so confused!?

Right, so I've met this guy about a month ago, he's great, really nice. He opened up to me about a disorder he has, a tics disorder. Hes on meds for this and i dont mind that because i never noticed until he told me. He recently switched meds as the previous ones didnt work at all, his mood was all over the place and it even came to a stage where he said he didnt want to talk to me again, which upset me. He says he has meltdowns where everything annoys him and he lashes out at everyone he cares about. He has done this to me 3 times now, and although i know he doesnt mean it, i'm still really hurt and upset. And he expects me to forget about it and move on but i cant. I told him that i think he should wait until he's completely better on these new meds before we meet again because these meltdowns are getting more frequent. I wanna be there for him but its so hard to be when you're told to f*ck off forever! What should i do?
