Feeling lost....

So the story is... been with my boyfriend for 2 months but i had my son from previous relationship he is 15 months now. I wanted another baby so jumped in it with new boyfriend im now 5 weeks pregnant. He does things that i noticed that i dont like sometimes he gets irritated at my boy a bit too easy or he makes noises or stuff that im kinda like ...why. just told my parents and their view is abortion. He doesnt have a job and has to move in to help me with new baby. But im kinda in the mind that i think i van do 2 kids on my own but dont really want the attachment of a guy.... it might be coming accross wrong but can anyone give me any insight please. I dont think abortion is an option as i cant even bare the thought....
