I think I'm going to look through my boyfriend's phone.
Why are going to look through his phone?
I want to be sure that he's not cheating on me with someone else
That is not a good things to look through your bf's phone. It could end damaging your relationship if he finds out.
I don't care. It is my lover and he should not be hiding anything from me.
But shouldn't you learn to just trust him instead? That way you wouldn't have to live in fear of him cheating on you all the time.
