Chickychoccyegg - its also not fair to op for lots of people to be over dramatic, he asked a question, she answered, thats about it really, maybe he is contolling and weird i dont know, but theres not much in her op to suggest he is.
Got a text at lunchtime saying ..why aren't you at work like you said?
You are the only person who thinks this is innocent. He's not just wondering why she was in town, it's in the nuance of how he asked her. He's accusing her of not being where she said she was. If it was innocent, he'd have said "Oh, x saw you in town earlier." No questioning, no accusing her of lying, just a simple statement.
I read OP's posts to my DH, and before I'd even finished, he was saying "Oh dear, that's not good, she should leave him." Even he could see this was wrong, and the only experience of abuse he's had, is me telling him about my experiences.
This is how abuse usually starts, little things that could be explained away, and that other people who haven't experienced abuse, won't recognise for what it is.
