Just curious cuz my SO does and I don't know his code..it makes me wonder what he's hiding from me.. I just have a bad feling but maybe it's because the trust was broken for awhile due to him talking to other women on Facebook. He as changed a lot and doesn't go out like he used to but I am still worried..we are about to have are first child together in 8 weeks and it has changed things but still didn't stop hm from talking to other women on Facebook. I just feel like something's not right..does ur SO have a code so you can't get into his phone??
