Okay vent time :/ I don't know what to do about my husband.. I understand he's 20 years old and wants to be young but we have a baby due in 3 months! You can't just call into work because you're too tired. I feel like all he wants to do is stay home to sleep, smoke pot, and play video games. there's no legit reason to be calling in. He only worked 3 days last week and none this week... he's gonna get fired and he's not even concerned. I don't know why suddenly out of no where he's become so irresponsible... I'm beyond stressed out and pissed off :(
