Happy Mother's Day to me ... i guess

So I posted here about a week ago about my Q (bf) relapsing and hiding his drinking and making me miss work. Well, I was right, he did relapse to his meth addiction as well and I have been dealing with his weird addict behavior all week. He has pretty much been making my life and son's life miserable. Keeps picking fights and then calling me crazy and psycho. My poor son (3yo) is so confused with his behavior and my anger.

Today was the last straw. I woke up at 3 am to him pacing and acting weird in the living room and gave him nyquil and told him to fall asleep. Then my son and I went to his little art class in the morning and then brunch for mother's day. When we came back home, he had locked us out of the house by locking the top deadbolt which can only be opened from inside. I kept banging the door and freaking out my son, until he came to open it. He had been doing weirdo shit in our living room, had blankets on the windows, and the house stunk. Those who know what meth heads like to do under the influence will guess what he was doing. I unleashed all the rage and told him to leave. I stood there and told him to pack his bags and go. Enough is enough. He relapsed a month ago and I knew but he kept saying he didn't, yet all signs pointed to yes. I told him just as easily as he went out to find drugs, he can go back out and figure out what to do next. I emailed my landlord about what I can do to remove him from the lease. If I have to be explicit, I will tell them all the truth. I have kept it from everyone because I was ashamed, but this is not my shame, it's his.

He couldn't stay sober for his family, well now he doesn't have to worry about one. He tried to use our son against me saying "don't make me leave my son" like he even cared when he was out for days getting drunk and high, but NOW he does. I promised him this would happen if he relapsed again, this time I am following through with my promise. He is out!

So that is how he thought my mother's day should be celebrated; dissolving our family, scaring my son, making me livid, and now I am alone with my son... Peacefully alone with my son... Until he sobers up and decides he needs us.... F that!
