Slow and tried but true, 2 ways to catch a cheater.

Trying to catch someone cheating can be time consuming.  Do you trust your gut instinct or do you want proof?  If you find evidence of an affair do you talk to him or just leave him?  What if he lies to you and it's believable?  What if he keeps cheating?  How much time are you willing to invest to discover the truth?

For me, I love the thrill.  How many different ways can I discover secrets?  Who is more clever?  How many different books can I write using all the information I gather?  The answer to that by the way is three in the works so far.  The least I can do is make some money out of this whole ordeal.  That will piss him off once he learns what I did.  Good.

However, I don't recommend that to anyone.  I, on the other hand, know that I should've left years ago when I first started to wonder why his personality changed. Also, I am a covert passive aggressive woman.  He is a covert passive aggressive male.  In other words, together we are a screwed up, dangerous couple.

Let's get back to you.  Are you going to trust your gut (which is really your subconscious having noticed clues) or are you going to look for proof?  If so, how much time are you going to allow yourself to look?  It can be time consuming.

Looking online for proof of cheating, lying, infidelity, unfaithfulness, what ever you want to label it, can suck up your energy and time.

Dating sites.  If he's at least half smart he won't post an image of himself which would make it a lot easier.  Other wise, type in a description of what you are looking for (his age range, physical description, an approximate mile radius and qualities you think he'll use to describe himself.)  Now you have the tedious task of gleaning through all the profiles.  If you run across your partner's profile you'll know.  Be sure to search through slutty dating sites (adultfriendfinder, adulthookups, naughtydating for example) as well as, the regular dating sites such as match, plenty of fish and zoosk.  You never know, you may run across an image of your man's junk.

Searching dating sites is the most time consuming method I know to find clues, but when you find it you can set up a fake profile to start "flirting" and maybe get a chance to bust him face to face.

Follow them.  This is very old school but it works.  You may want to ask a trusted friend to help with this.  Figure out when he meets up with the mystery woman.  Is it on his way home from work?  When he's at "the gym"?  When he's with his "friends"?  Instead of going to church?  Once you know when then you can make plans to follow him and see where he goes.  Or if you have the money simply put a gps tracker on his car.

Time and patience are key with these methods.

Remember you are deserving of respect, love and faithfulness.
