Remember when you were a kid and summer meant no school, freedom, and fun? Well, that attitude carries over into adulthood, leaving us with the sense that during these months, the usual rules don't apply. "Some men take this to mean that it's okay to cheat once the hot weather rolls around," explains Daniel Kruger, PhD, evolutionary psychologist at the University of Michigan at Ann Arbor.
And let's not forget the obvious: When the temperature goes up, clothes come off. Since guys are so easily turned on by all the female skin they see poking out of sundresses, tank tops, and short shorts on the street and at work, they're in a constant state of heightened desire. As a result, it may be easier for them to succumb to lust should an opportunity arise.
3 Signs He Could Be Straying- Watch out if he doesn't invite you to a work event that other coworkers' partners are attending, like an office picnic or rooftop drinks. "Not inviting you implies that he doesn't want his coworkers to know he has a girlfriend so he can flirt with someone else," says New York City therapist Diana Kirschner, PhD, author of the forthcoming Love in 90 Days.
- Though it's normal for guys to check out other women for a second or two, even if you're right there with him, be concerned if he's taking "more than a quick glance in front of you. It's a sign he isn't concerned with appearing faithful and may be open to playing around," says Kirschner.
- Take notice if he tells you that he wants to use his summer vacation to take a guys-only trip and doesn't set aside any time off to spend with you. True, he could really just want to hang out at the beach with his buddies. But he could also want to mess around out of town, where he's less likely to be caught.
