He's been to prison before. Why would this time be different?Absolutely agree with this. A break from her now could be the making of him. He could get recovery support in prison and also support to learn a skill.
Ste is, as always, an opportunist. He's robbed friends plenty of times, often using force to get what he wants. Whether that's to fund an addiction or jsut because he got the chance while someones backs turned, it doesn't matter. The man has no remorse and no character. The only reason he's happy to "own his mistakes" is because he doesn't give a do about his mistakes.
