OK, so not sure what to do here. My wife and I have been together for over 10 years, married for 5. Last week I opened her bedside drawer looking for some antihistamines and at the back found a 2 pack of pregnancy tests, with one missing, assume used. I should also mention that I had a vasectomy over 15 years ago and whilst our sex life may not be the whirlwind it was when we were younger, we still average 1-2 times a week.
We don't have kids, none of her girlfriends live close by and whilst I keep telling myself there must be an innocent explanation, I'm really struggling to find one.
It's eating me up inside and whilst I know I should simply ask her, I'm worried that whatever she says will either "make it true" or I won't believe her and then it's "out" and I don't know how we come back from that.
I'm also thinking of the wider implications, we're in (what I thought was) a trusting relationship and so haven't used protection since shortly after we got together. Now all I can think is was this a one off? Is it a regular thing? Is she having regular unprotected sex with someone else? Doesn't that also put me at risk from STIs?
Not sure where to turn, can't really speak to friends or family, what do I do?
