I'm a 48-year-old man, and I'm growing more and more suspicious of my 38-year-old wife. She's suddenly been staying late at work, dressing up more often, and recently went on a "work trip." Am I just imagining things?

Lately, my wife has been putting in a lot of hours at work, claiming she's trying to earn some extra overtime pay. I'm usually not the jealous type, but something feels off. She spends most of her days at work, and when she's home, she's often preoccupied with the kids and seems to be ignoring me. I've shared my feelings with her, but she brushed it off by saying we really need the extra money. Here's where I start to question whether I'm overreacting. When she came home from work today, she informed me that she accepted a 'project job' that will keep her away for three weeks. I can't shake the feeling that she might be having an affair or at least using this as an excuse to spend time with someone at work. It strikes me as odd that I express my need for more attention and she responds by committing to a job that requires her to be away. Her justification is the financial benefit, as she'll be working for 18 straight days with long hours. I truly adore her, but I feel like our relationship is losing some of its spark. I worry that she's overworking herself and needs to take a break, or she risks burning out. I'm doing my best to support her: I handle the kids, cook meals, and help with the housework, yet she hardly acknowledges my efforts. Now, I'm starting to fear that she could be involved with someone else or clandestinely having an affair, especially since she's been staying late at work, which was never the case before. Her increased hours seem suspicious, and while I’m aware of the financial gain, I can't shake the feeling that there’s more to it. Another concerning factor is that she's been consistently going to the gym during her lunch breaks at work for the past six months, often wearing really attractive outfits. One day, I even saw her in a rather revealing lacy underwear. All of these signs are overwhelming, but I can't be certain, and I also recognize that we need the income. I find myself feeling anxious and on edge; I’d love to have a drink to calm down, but I’ve been sober for so long. I just need to know if I’m being paranoid or if there’s a valid reason to be concerned. Is there something going on that I'm not aware of? How should I discuss my worries with her? P.S. I want to clarify that I’m not solely dependent on her income. I also contribute financially through my work at convention centers, birthday parties, and events as a magician and performer. While my work isn’t always stable—especially with fewer birthdays in January—I’m also starting a podcast called "Basketball and Chill" to cover the NBA, WNBA, and pop culture, which means I'm busy supporting our family financially, not just handling household responsibilities.
