Vent... No help at all.

Need to vent.... So fed up with not getting any help from my boyfriend. We have 3 kids, we each have a daughter from previous relationships and now we have our daughter together. I get 3 girls is a lot to deal with and our daughter is very fussy and colicky but he just doesn't seem interested in being a father.  I take care of our daughter all day and wake up throughout the night to feed her and on top of that I take care of my 3 year old.  When I ask for help he throws it in my face that he makes the money in the house because I'm a SAHM. Like what does that have to do with helping me take care of our child?! I'm so frustrated and sleep deprived it's so upsetting.
