It’s funny how he could send a perfectly spelled message initially, then total gibberish, then another okay message.
I bet his blood ran cold the second he realised it had been sent to you, then he messaged gibberish on purpose to make it look like he was out of his mind drunk (easier to pretend he doesn’t remember the first one then), then conveniently stopped the gibberish to message you again.
Sorry to be so cynical but I can’t think of any other reason at all. He was at the station so not still drinking, and even if he’d been at the pub he wouldn’t have got so much more pissed in the time it took between those two messages.
The deleting confirms it. He’s cheating. I’m so so sorry. The fact he has tried he whole ‘i don’t know/remember who it’s for’ then just changed the subject shows his guilt so clearly.
If I’d sent an innocent message I’d have no reason to delete my texts. I certainly wouldn’t delete them if there was something that could be construed as dodgy. And if this was me and my partner had even the smallest suspicion I was up to something no good, when I hadn’t, I’d be moving heaven and earth to prove I hadn’t, reassure him, access call logs, give him details of who I was with to corroborate, provide info I couldn’t have faked (like some current details about where I’d been, e.g. the bar’s specials board!). It’s never happened to me cos I’ve never cheated but I’d be so keen to prove my innocent to put his mind at rest.
I wouldn’t just play dumb, delete the evidence, and then change the subject by talking to someone else.
I’m so sorry. If it walks like a duck, quacks like a duck, it’s a cheat.
