I just need to vent right now

So im 39 weeks and my contractions have been getting stronger. My husband has to go to his dui class and all of a sudden he starts getting in his little moods and starts saying the house is a mess and hes getting an painc attack and im just sitting her staying quite letting him vent while im trying to time my contractions and entertain our 1 year old and making sure our older kids are getting ready to shower and ready for bed so bed he left i got up and started cleaning the house and still contractioing it gets me mad because the past two days his friend has been calling asking for rides and he jumps up and goes but when it comes to me and the kids all he does is say hes sleepy and gets frustrated with the kids and snaps at me for everything i just want to break down and cry because ive been uncomfortable wit these contractions and my daughter just wants to be with me and i pick up my older kids from school but i know sometimes i gotta cut my husband some slack hes been working alot of hours and doing the laundry lol but today just pushed me over the edge
