Lying bitch....

Nina
So I'm recently pregnant, my husband and I have spent 2 years ttc, so of course I have HCG tests everywhere in my bath room. My most recent one I took this morning. Is now missing.... Normally I would of just assumed my husband tossed it, but after asking him and confirming he didn't I'm now thinking its something else...
My best friend is a bit shady and kind of a huge bitch, so I wouldn't put it past her. She's been talkin about "trapping" this guy for a few weeks now and all of a sudden today she brought up she might be pregnant, and came to my house to take the test, and my most recent test goes missing... I don't want to jump to conclusions but I feel she took the test to (in a couple days) turn around and go "hey I'm pregnant" to get this guy to stay... Now I'm going to tell him, cuz this is wrong, but idk if I want to wait till after she says something, or if I should warn him before hand... I guess the bitch in me wants to see how it pans out... But I'm having a moral headache trying to decide if telling him now is the "right" thing to do... Why are some women so fucking shady and deceiving... ?!
