I mean how to find out if she has had or having an affair.
Look for the classic signs first - is she hiding her phone? Changing her appearance? A new friend she suddenly talks about? Sex - has it stopped altogether or dramatically increased? If you gut is telling you something isn't right, then it usually isn't.
You could snoop. You could go such lengths as get recorders. Or a PI. Some say don't, some say do. For some, cheating is the final straw...trust is hard enough gain but almost impossible to restore.
In reality, does it matter?
What you should be doing is working on yourself. This may be sucktastic to hear, but you need to pretend as if she doesn't exist at all. Become the best you can. Do new things. Go new places. Put her things away so they aren't a reminder. Whatever it is, do it for you.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
