Needing some mom support

So I'm about 11 weeks into my second pregnancy with a crazy active 14 month old boy already. And I'm feeling a lot like I shouldn't go through with this pregnancy. My step mom is not happy about this second baby and thinks it's too soon. My boyfriend and I are tight on money so I got a part time job to save a little before baby comes along which I am perfectly happy to do and miss working anyways. But as I'm looking for some kind of childcare for the nights he's working and can't watch our son he's just shooting down all of my ideas, hes not comfortable with a babysitter coming to our house. Or not comfortable with one of my girlfriends watching him. And my step mom has completely shot down the idea of them helping before I could even ask. Just said "well don't think about asking your father or I, or your sisters to help while your working." And while my boyfriend shoots down all my ideas and I don't want to do something he's uncomfortable with he's not helping me figure out any other options that he is comfortable with. He just says it's my problem which I don't think is fair because he is OUR child and I'm going back to work partly to help OUR money situation. So I'm just overwhelmed and thinking that this second pregnancy isn't a good idea and I should terminate now. Just looking for some friendly mom advice.
