Brand new poster, I know my wife uses this so I thought I'd give it a go. Been with my wife for 10 years married 3. I adore her and to be honest have no idea how I have ended up with someone like her, stunning beautiful, smart, driven, sexy - basically everything you could want ! However recently her behaviour has changed massively. She changed jobs, to a much more male dominated sector of her industry - works in a male only office, all her clients are men. As soon as she took that role her habits changed. Took a much greater interest in health and fitness. She does not need to loose weight in the slightest. But over the space of 6 months started working out more and more, adjusting her diet, cutting back on booze. Now she works out every day with her boss, who himself is a married man. She looks amazing, however I can't help thinking this is maybe a sign of something else. We have had a hard year, trying to have a baby without any luck. The next step is IVF due to our age, which I've always said I won't do as i have seen it ruin marriages (the cost, the stress) I have a child, who lives with us part time -they have been clingy and challenging recently, which my wife can struggle with. My ex has needed extra support finically due to problems in her life, my wife hasn't always agreed with the level of help I give. She tells me the exercise help her deal with the stress of the year and wanting to look good for me. AIBU to think maybe her head has been turned at work (god knows she will turn plenty!) if this was your husband would you be concerned?
