Quoting whack a mole crazy:" In our town they do straight up investigations just to bust you. I dont want to be anywhere near it because ... [snip!] ... My boyfriend is 18. So i know he is still going to act imature but damn. Im 33 weeks pregnant and hes acting like a douche."
you are making excuses for him. His mom isn't evil to do anything to get him into trouble. She's trying to get her smurf of a son to grow the smurf up and act like a man.
you both have a LOT of maturing to do in the next 7ish weeks. You need to get out of your denial and away from the pot head. This is not the example you want to set for your son.
