I don’t even know what to think...

I’m posting anonymously because it’s honestly embarrassing and I really don’t post on here often anymore but...

My sons father and I have been on and off for almost 3 years. Before our son it wasn’t the greatest relationship, he has combat PTSD and he resorted to drugs. After our son was born it continued, then when our son was 3 months old he left to get help. He bettered himself, he got clean, got a job, bought a vehicle, etc... I didn’t see him for 10 months. He came to visit us a week ago and that’s the first time I’ve seen him since he left. Things went great but he had to go back for work (which he was living 9 hours away). Then he was down there for a few days and ended up getting pulled over for speeding, he resisted arrest and spent the night in jail. So that caused him to lose his job. So he moved back home (we aren’t from the same place). His hometown is 3 hours from me, but that’s better then 9 hours so I was happy. He literally moved back this past Friday. so he hasn’t been home for a week. Things were okay at first, he was actually supposed to come pick me and our son up tomorrow morning and we were going to spend a week out there with him. Well the past few days he’s been distant and we fought and didn’t really talk but I still planned on going. Then today around noon I got a phone call from jail. He got arrested AGAIN last night. He told me he was sitting in his truck somewhere drinking and they arrested him, which doesn’t make sense but I didn’t feel like fighting so whatever. I had to call his grandma because I obviously dont live there and can’t help him. Well she spoke to an officer, and turns out he was drinking & driving, open container, resisting arrest and something else I can’t remember. I’m sick. I can’t eat. I gave him this chance and this is what happens. I was supposed to be packing to go see him tomorrow. Does anyone have a general idea of what the penalties for these things are? I don’t even know what to think.
