So me and partner have been together for 4 yrs nearly we have two beautiful daughters. The other day I was getting DD car seat out of HIS van and found a condom in the door compartment. I asked him and he said it wasn't his. We've been having a lot of arguments in the last week and I didn't want to argue again so I just brushes it off. But deep down it's killing me. The use by date Is 2013 and I googled life span and it says 5 years so I trying to convince myself it's very old. I just don't know what to do he says he wouldn't do anything to jepeodise our relationship and he loves me a lot. I feel sick with worry
