Quoting Tat'd Bitch+3:" It expires in 2016"
Expiration dates mean little though. I imagine condoms last a while. What you really need is the date they were bought. I imagine there's not a receipt with them though, lol.
Like I said, there could be a million excuses. Don't assume he's cheating unless you have solid evidence. That's not fair. Imagine if he found a guy's watch in your drawer and it really just belonged to your best friend's boyfriend who had left it at your house the last time they were over? Wouldn't it upset you if you got accused of having a boyfriend on the side just because of that? Just think about being in his shoes too.
It always pays to be vigilant but don't go overboard.
