@Sick in Love,
If my wife and I was using cond0ms and she found some in a jacket pocket in the same manner you did, I do not think off hands she would assume I was hiding them so that you did so assume is kind of telling about your trust levels to start with in the relationship.
Hell I do have some condoms way back in drawers and perhaps other places that are way pass there use by dates and I do not think my wife coming across them even those we do not used condoms would think they indicate anything other then that I never clean out my drawers and am not a good housekeeper.
In fact I can just see her asking me with a smile if I was keeping these as souvenirs of my past.............
In any case if he had not come up with some silly story about testing you that is an insult to the intellect even with two condoms used out of a package in a jacket should not had been all that worrisome to a secure wife/girlfriend.
You do seems to have a problem base on that story of his, but you did not have a solid relationship before then if you was thinking in terms of him hiding thems when you first found the package.
