Did i do the right thing? leaving him?

After my bf found out his mom had cancer about a month ago he said we should take it slow and not rush and i have not seen him much as i used to and he says i shouldnt put a title on where the relationship is going i should just let it flow because he doesnt like finalizing things....he still talks to his ex of 8 years as friends because theyve been close but he told me hes confused and that maybe i should unconfuse him but yet he calls me to hangout and kisses me and says he likes me alott ...what can i do he also gets jelouse if i were to talk to another guy . I wrote him how i care for him and that i just cant do this or ill get hurrt in the end and all he put is a sad face like this :( nothing else i didnt write back but why did he just do that then today he wrote you dont wanna talk to me? and i wrote i just dont want to put my self in a situation where ill get hurt and he didnt write back! why is he doing this i dont get him what does he want from me?? anyone have any ideas help does he still want me or?...does he care or not plus when i hang out with him he always tries to get intimate with me like hugging touch gettting hot why wont he be exclusive? he wont even give me an answer why?? i need an answer from him
