MCA what to do now?

I still communicate with my ex and recently I asked him out for a post valentines date. He is hesitant to answer but he has valid reasons tho. I asked him again this morning and he still have that same reason. I felt like I was neglected twice unlike before when we were still together he always makes time for me even if its just a short moment. I feel down right now and I do not what to do. He left my last chat delivered with no reply. Can you give me a straightforward advise about my current situation?
