Yes it happens
Aww :( that sounds sadist but he is well , he might be tensed or frustrated about something .. Check it out talk with him and see weather he is emotionally and mentally ok?... I know its though for u coz even u need his emotional support
Dump him he doesnt repects or shows love to you .. Move on
Thats sucks :( but I suggest coz it might get worst so
Aww :) it shows u love him so do onething be normal with him but when ur togesther make him remember about things u use to do or how u met in past
Aww thats so bad about him :( does he always behave to annoyed?
Awww :( he sounds very frustrated and he is facing some difficulty or something he hasn't told u yet.. Make him talk to u untill he doesn't sounds normal he wud behave the same.. Watch out on his activities :)
not with a human being..
