boyfriend troubles.

i'm 24 weeks pregnant and i've been catching my boyfriend being sneaky, and he's been hurting my feelings too. First i see that he all of a sudden is following his ex girlfriend that i blocked off his account, so that means he took the time to unblock her and then follow her. why do you care what she's posting so much? than when i brought it up i tried to be fair and tell him how if i did the same with my ex he would freak out, (cause he would) and he was like "if you think i'm gonna sweat a bitch you're wrong, i don't care do what you want" which really hurt me. so i'm just some bitch?? i'm having you're daughter, and all i am is just some bitch to you? and ever since every time we argue he just tells me how much he doesn't care about what i do and how he is not going to sweat it. I mean am i crazy for being upset?? is it my hormones or does this seem a little mean to you guys too?
