My Partner uses the train alot but the last time he came home with some womans mobile number, he said he'd met her on the train (so at least I didnt just find it, he did tell me about it), he said they'd been talking and he'd helped her with her bags but is it really normal for him to go and get her mobile number?? they were then txting each other and he told her we would go to her pub on the saturday night (despite us making other arrangments!) and then went in a mood when I said I didnt want to go and text her to say he couldnt make it afterall... is this normal??
