Pregnant & single

Liana
i got pregnant in october with my boyfriend. since then he has been cheating and lying. not even coming to see me, only to have sex. he didn't come to my first 3 appointments for the baby and then had a sudden change of heart and "said" he was so excited about the baby. after knowing he's been cheating on me for months and still staying with him because i keep believing his lies i have finally left him today. the only person i need in my life is my daughter. he doesn't ask about the appointments i have to bring it up. should i tell him about the upcoming appointment tuesday or should i not say anything unless he asks? i'm trying to have as little contact with him as possible so i don't fall back into his trap and still trying to figure out the right thing to do.
