But again, we don't KNOW he set out to get pissed. We don't know how long he was planning to be out after drawing out the cash for the babysitter - half an hour (one or two more drinks) or an all-nighter? I'd guess closer to the former.
Yes he didn't let her know. I'd expect a text, but the OP has no phone. How did he think things would turn out? If he'd come back after say an hour (including time to get the babysitters money) would the OP have been worried? Probably not. If you read her first post she says she thought he'd gone for a couple and only got worried once hours had passed and he didn't turn up. He didn't intend to get his card stolen, or end up in a cell. Yes, it's not good. But it doesn't necessarily mean he has a problem with alcohol. People make mistakes. I have a friend who holds a v senior position in a firm. Drinks rarely. But once got so pissed she started a fight (with a man, unprovoked) and was lucky not to have been arrested. Not something she does regularly, or ever. But it happened.
And all this he's got alcohol issues stuff really only started once it was clear he wasn't on drugs/ with the babysitter or a prostitute. Posters have the bit between their teeth that this man is shit, the OP should ltb, and because the sex/ drugs turned out (surprise, surprise) to be wrong, and the attempts to pick holes in his getting his cards nicked/ getting arrested also didn't succeed, now we're on to alcohol.
If the OP came back and said he'd never drank, this was a total one off, then the same posters would be on to him wasting the family money or something else.
People really just need to let this go! The OP posted for support because she was worried and scared and there was no one she could contact. She didn't post for her relationship to become subject to forensic analysis ffs! Let's just stop all this now. So some posters wouldn't be happy. Ok, up to you. I'm sure your DH does things I, or the OP, wouldn't be happy with. The OP hasn't asked you to comment on her relationship, so why are people still doing it? Because he has to be proven and found to be on the wrong, somehow.
