Phone lock code...

Let me start off by saying me husband and i married young and had a rocky start, and some bad times since. I found some things out literally right after geting married that if i had known before, we might not have gotten married so quickly.

So I just went to unplug my husband's phone from the charger and seen that for the first time in over a year he has a lock code on his phone.

I'm really upset and something just doesn't sit right with me about it and honestly makes me nervous. I'm not sure how I go about asking him why he has it because I feel like it will just be some excuse and not a real, honest answer
