My Advice
Tip #1(Don’t be Insecure) Opportunities to cheat become a little more plentiful when it’s hot outside.
But that doesn’t necessarily mean your mate will cheat on you. Don’t assume the worst, plan to be the best. Re-introduce some of the qualities that attracted your mate when you guys first start dating. This not only emphasizes the positives aspects of your relationship but also reinforces to your mate what he or she may be losing if they ever decide to jump ship.
Tip #2(Pay Attention) Lack of attention; real or perceived, can be a major problem in a relationship. The most minor things, like not noticing someone’s new hairstyle or answering a phone call with a text can be seen as a sign of apathy. And if your mate thinks you don’t care; then odds are, they will find somebody who does.
