Fuck.....long post alert....
How much do you trust your partner? I think I maybe only trust DH 90%.
Recently found an empty blister pack and an almost empty blister pack (7 gone 1 remaining) of viagra in his wallet. I was trying to cover my tracks after washing his wallet by mistake so not intentially snooping, just trying to dry everything before he noticed .
Ive never snooped before as never felt the need to.
I was pretty shocked by the discovery not because I give 2 hoots about people taking viagra but because I dont think dh needs it. I’ve also not really noticed any difference in performance and we havent been that active recently. We are not communicating very well and have hit a rough patch/arnt getting on. So I have a bit of a bad feeling that the viagra might not have been for my benefit 
Think I have issues/anxiety re trust possibly due to my parents ‘perfect marriage’ crumbling overnight and my dad being a serial philanderer/not the person we thought he was. So this has impacted on me not trusting DH or anyone else 100%. I dont want to be naive/ put my head in the sand which I think my mum did (not that I blame her). So my default is suspicious/ not a push over or maybe I have serious trust issues?
We have been together 15 years, married 10 I honestly trust DH a lot, just not totally. Could there be a rational explanation? Is this a normal secret to keep? I suppose he could have bought for our anniversary weekend away a few months ago but he never mentioned it.
I just cant shrug off the doubt. Why would he not tell me if its for us? Is it wrong also to think its a bit sleazy ie that he wants to improve his performance/enjoyment? I just thought we could have spoken about if there was an innocent reason.
Urgh do I confront him? Casually speak about viagra?! Go all Nancy drew on his wallet and monitor it, see if the other one disappears? Further snooping?
