2. No emotional connection

When you’ve been with someone for a few decades, it’s understandable that routine might come into play. But if everything is good and suddenly your partner treats the act as another task he can tick off, rather than trying to bring a bit of fun and passion into play, it might be a sign he’s cheating on you.

When someone is secretly involved with another person, they will still be a part of their primary couple, but their minds are more likely to be elsewhere. This can be shown during your romantic times, and you’ll notice your lover avoiding eye contact, rushing through the experience, or not caring about ensuring you have a good time.
