How To Find Out If Your Boyfriend Is Cheating On You Using CSI

Step 1: Finding Fibers

Locard's exchange principle states that when two objects come in contact, a cross-transfer of materials occurs… and when clothes come off, so do tiny clothing fibers. Offer to clean his car, as a special treat. Open the passenger-side door.

Turn on your black light. Sweep the blacklight over the seat. If your partner doesn't car pool, and never has time to take you out, you shouldn't find any fibers there. But if you don't own hot pink hot pants, someone else has been riding shotgun. Check the back seat of the car as well.

Step 2: Semen Search

This is not for the faint of heart. If you two haven't been intimate lately, it's time to examine his underwear. Start with a clean sample.

Tell him this new pair of underwear you got him is hot, that Brad Pitt wears them and they would look so very good on him. If it's become his priority to be sexy outside the home, he'll wear them.

When he comes home after allegedly "working" late, find a way to discretely examine his underwear. If he ejaculated during the day, it's likely there will be a drop or two of semen. According to forensic scientists, when semen dries, it leaves a transparent, stiff, residue. It look slightly yellow on tighty whities and smells a bit like bleach or chlorine. If you're still not sure, use your blacklight.

Step 3: Hair Analysis

When two people come in contact, hairs from one person's body may attach to the other's. Massage his feet until he's deep in sleep. Then crawl up slowly and pull down his underwear.

Take a fine-tooth comb, the kind often used to find lice and other small creatures, and comb through his pubic hair. Search for any loose hairs. If you find one that doesn't match his hair color or shape, you've got him.

Step 4: Make Your Case

Find a time when you know you'll have his attention, like during the playoffs. Present your evidence calmly. At first he may be defensive - saying "Some other dude did it". As you present more evidence, his defenses will weaken, and if he's any man at all, he'll confess and profess his love for you.
