Would I be wrong if....?

👑 Aaliyah • 20 🍭 Pisces ♓️ Bisexual 👫 Atlanta 🍑
Okay so, I just wanted know would I be wrong if I didn't tell my boyfriend I'm pregnant until AFTER the child comes? 
• Before you jump to conclusions and say 'Yeah, he should know so he can be apart of the pregnancy', let me give you a little rundown on him. 
• I'm 19 ; He's 20 {{ & as of right now, I'm not pregnant, this is just for future reference }}
• But anyways, we met back in January and started having sex in March ( each time without a condom ). He doesn't want kids right now because he's young and isn't financially stable and I can respect that because I agree with him 100%. But every time I bring up "What if I get pregnant?" He says, "Then I'll give you the money for an abortion." #PumpTheBreaks That's where I drew the line at. I am in NO WAY, under any circumstances for abortion. It's just not my thing -- if you disagree, we can argue about that later 🙄. But THEN, he told me ( since I wouldn't get an abortion ) He would punch me in the stomach to get rid of it 😖
• I feel like if WE were bold enough to lay down and constantly have UNPROTECTED sex then WE should be responsible enough to take care of a child. I told him honestly, "If I ever get pregnant by you, you will not know until AFTER my child gets here." 
• Now if I did get pregnant by him, his thoughts and views about it could change but I didn't want to take any chances so I just decided I wouldn't tell him. He isn't the worst person in the world, but because of his fucked up opinion, I did leave him because he obviously wasn't mature enough to take care of his responsibilities.

So ladies, I ask again ;; WOULD I BE WRONG IF I DIDN'T TELL MY CHILD'S FATHER I AM PREGNANT?
