10 Things To Stop Doing If You Think You May Cheat

2.  Stop Meeting With Old Flames

Stop connecting and spending an inappropriate amount of time with an old flame in person and/or online. If you don't think you can avoid be tempted by someone from your past or someone you meet on Facebook or other social media, then delete your accounts. Your marriage is more important than these "old friends."
Dr. Susan Heitler: "If you don't want to catch fire, stay far from the sparks. They are fun and often prove too dangerous to be worth the mini-delights of minor sexual pleasures. The two highest risk categories for dangerous connections are old flames and current business associates, especially ones that you spend a lot of time with."
