Is it normal to not be over him after 6 months

Hi ,G and I were acquaintances for about 5 years, a little more than that, maybe even friends, anyways just last year my life became a turmoil and he is going thru a nasty divorce, we started talking and became more than friends, but less than lovers. we "dated" for a month and he went away to some spiritual retreat, and when he came back he was all distant with me.

we used to text like 70 a day, constantly, talking etc. he told me he was fallen for me, and was i his etc etc, and he even gave me songs that he says was "our songs" he even said he wanted a child with me and even picked a name. he wanted to combine our famlies etc.. he even told his brother and best friend about me so i thought, well a good guy, know him for a long time, im fallin for him too, well after we had another one of our dates where, we kinda sorta had sex.. well it wasnt really.

the next day or so later he started becoming distant with me, he said he couldnt be with me since he is married and he is afraid he is being followed becus of the divorce proceedings. he says he has too much on his plate right now and dosent want anything else besides a friendship. he blocked me from his fb, and just stopped.

he also broke up with me over the phone day b4 my bday. my delimma is, why would he do all that if he wasnt serious, or was he serious and got freaked? ive asked him and he said that he just cannot risk anything now. that after his divorce we will date again, wants to be friends, but he nvr txts/calls me, even as friends. why cant i get over him? its been 6 months... sum1 help me pls
