How to Know If Your Girlfriend Is Cheating on You

In a relationship, there is nothing more heart-breaking than finding out that your girlfriend has another man--unless, of course, you didn't have a clue it was happening and are completely blindsided by the news. If you suspect your girlfriend is cheating on you, there are a few things that might give her away. But you may have to use some unconventional methods to find out the truth. Read on to learn how to know if your girlfriend is cheating on you.

Step1

Ask to borrow her computer or cell phone. It may seem like a small thing, but if she has another guy on her speed dial, she won't let you anywhere near her phone or computer. Make up some excuse about checking an online auction or losing your phone, and then evaluate her reaction.

Step2

See if she's really working late like she tells you. Call her at 7:00 p.m., for example; if she doesn't pick up her phone, try again in 15 minutes, then send her an email. If you don't hear back from her within a few minutes, she probably isn't at the office. If she's an hourly employee, check her pay stubs to see if she really is racking up the overtime.

Step3

Check for a paper trail. While not the most upstanding way to go about it, if you have suspicions, you can check bank accounts and credit card receipts for strange transactions. This may be tricky if her boyfriend pays for everything, but you may see some deposits that aren't supposed to be there if he's giving her money for rent or bills.
