I'm so over this inconsideration !!!

Does he even CARE . My sons father won't come meet my mother I'm currently 6 months pregnant , in my culture it shows a sign of disrespect . Almost like he just doesn't give a fuck , he promised he would come . & after not hearing from him the WHOLE DAY !!! I called him to near a bunch of excuses . He doesn't support me in ANY WAY . I tried to give him space and thought maybe he'll come to his sense and that didn't even work ! What do I do ! What an assss !!! I'm so frustrated it's pretty sad , considering I have been there for him and the little I want or expect from him he continues to disappoint me !!!!!!!!!
