Maybe he took the Viagra to see how it felt. Maybe he took it to experience it for himself, by himself, after he got home from work. You’re assuming he felt the results at a certain time, but are you sure?

I can make a bunch of guesses about how he used it and why, but he’s the one with answers. Let him know you saw the pills in the truck. If his libido is something you’ve already discussed, this shouldn’t be the most complicated conversation.

My question for you is why you’ve jumped to the conclusion that he might be cheating. That’s one of many possibilities that could have popped into your brain, but it’s the one you chose. It makes me wonder about the rest of the relationship and how his diminished libido has made you feel. Are you lacking intimacy in other ways? Has he seemed less engaged?

It’s time to figure that out for yourself. Because you can ask him if he’s cheating and he’ll probably say no, and then you’ll have to figure out whether you trust him and if not, why not. If you’re going to ask about fidelity, you want to be prepared to talk about why you’re so concerned.

There’s no perfect way to start the conversation – you just do it.

Readers? Tell me other reasons the LW’s boyfriend might have taken that pill while in that truck?
