How Do I Deal With A Denied Pregnancy?

I just found out am 4 weeks pregnant, i told my boyfriend about it and all he said was that i should get an abortion to keep the relationship going, or i may decide to have the baby without a father cause he is
not ready to be a father or take a responsibility of a father yet. He said he'd deny ever knowing me if i decide to keep the baby.

I dnt know what to do cause am strongly against abortion, i havent told my parents yet because they wont take it likely with me all.  My boyfriend also promised to remove me on his social network, like whatsap
facebook ,twitter and also buy a new set of network sim card so he won't have anything to do with my again. He even once threaten to run away if the situation become worst.

My Mum taught me sex education and warned me several times against it, she will be very disappointed in me. In as much as i know my parents would eventually be there for me, i have a strict dad that might disown me if I eventually let the cat out of bag.

 This is driving me so crazy i don't know
what to do. This is the guy i love so much, i never believe he could do this to me, am left with thought. I can only think of three thing ... running away with my pregnancy, committing suicide or taking abortions pills (but it will be against my wish).

Help!!! am so confused.
