Heartbroken Rant 💔

My SO was so close to graduating, and just like always be decided to smoke weed knowing they'll test him once school starts again. He asked me for some money to buy himself detox yesterday and I told him I couldn't because he had made a choice and would have to deal with the consequences. Now he's worried about being kicked out. & he seems to have started thinking I don't care about him, I don't know if we'll be saying any more. I'm so devestated because I'm 13+5 days pregnant. We were supposed to tell out parents soon, but now I'm scared that while I tell them I'm pregnant ima have to tell them ima have to raise this baby alone as well. It hurts so much and I feel like I can't concentrate at all.any advice is appreciated.
