I’m leaving my toxic relationship

Me and my husband have been married for almost 3 years. Lately he’s been lying about where he’s going, who he’s with, and deleting messages. I know this because he was deleting messages right next to me (dumb I know) I thought we told each other everything and I never in my life thought I’d be in this situation but he has gone back to doing drugs. I won’t say which kind, but I’ve decided I don’t want my daughter around that when she’s here. (I’m 25 weeks pregnant). Also, when he is like this, because this isn’t the first time he’s done this to me, he can be abusive and has in the past resulting in us separating for a couple months. I know what the right thing to do is which is leaving for good but I feel stuck. I know I get treated wrong but I still stay. I do it to myself and I know that. Well tonight he drove home drunk, high, and started screaming at me for “hurting” him and I realized that this baby inside of me is way more meaningful and and loved than any feelings I’ll EVER have for this guy. I’m packing my things currently locked in our room while he’s knocked out on the couch and moving out tomorrow. I’ve always pictured the perfect family but I’ve accepted that it will just be me and my baby girl. 😏
