I need to rant/vent... is it wrong for me to put my foot down an say I'm not cleaning anymore. my baby shower is in 15 days my house needs to be cleaned up the rooms need to be moved around for baby boy an I've been doing it all alone. now I work once a week for 6 hrs. but also have my girls 2 an 4 yrs old 24/7 like I do everything for them all day through the night. which yes it's my job as mommy. I'm also high risk for preterm labor with this baby an the only way I can clean is sit on floor Cuz it hurts that bad to bend over. I've been asking for help all month an my SO rather spend his time helping his dad an brother fix up stuff at their house or spend time fixing a motorcycle in my basement keep in mind there is no money at all that we have that can be put in at all he can't register it has no motorcycle license etc but it has moved to his main priority while im.here trying to get things taken care of an keep my girls company etc. am I in the wrong to be so upset an angry I cry over it or that I'm done I'm not doing another damn thing in this house or outside to get ready for my baby shower. end of rant sorry ladies
