He chooses his job over me...im so sad?

recently,my ex-boyfriend call me out of the blue and we get together again.after one week he acts weird.he kind of distant himself from me.and he told me because his new job is very demanding.at first he actually told me that it was his mistake asking to be together again.it’s not a mistake,but it’s just not the right time.so,he ask for a break up and told me that it is better for me to find someone else.I’m so sad and frustratedd.but I replied calmly telling him that if he needs time to think and if he needs sapce,I’ll give it to him.I just don’t want to be apart from him.I love him so much..he’s my soulmate I guess.the one that I’ve been looking for.then..afterwards,we seems fine on phone.but,everytime we set a date,last minute he will be missing.he won’t showed up,he won’t answer my call and he didn’t even tell me that he want to cancel our date.leaving me frustrated..so,after few times he did the same thing and obviously it hurts me a lot.I asked him nicely again,does he really want this?and he said he don’t know..he seems to runaway from everyone except for his friends.and he didn’t want to see me because he didn’t have the answer to our relationship..so,I asked to think and decide.and last 3days he told me that,he need to focus on his job and he ask whether we can just be friends in the meantime?and I said ok..I don’t want to make things worse for him and for me..but right now..I don’t know.does it mean that I’ll be losing him forever?will I only be his friend forever?what should I do?
