I'm going to snoop on my fiance's phone so I can find out what he's really been up to.
What do you think he's been up to?
I think he's been talking to someone else because he keeps saying he's hanging out with his friends.
You shouldn't snoop on your boyfriend's phone because that's an extreme invasion of privacy. You should trust your boyfriend when he says he's hanging out with his friends unless he's given you a reason to not trust him.
We are getting married and he's been acting shady lately. I'm going to find out what he's been up to before we get married.
I understand your suspicions but it's probably nothing. If you really feel like he's been cheating then you should bring it up to him before the marriage.
