<human>: Summarize the given text in a few sentences.

I've been dating him for two years. He used to be real douchey and constantly used to send messages to other girls saying he wants to fuck them, do other things ect, though I know for a fact he hasn't cheated. A lot of other girls I spoke too said a lot of guys do this. He's stopped now (it's been two months(I think) but is it wrong that I want to look at his phone and his facebook? Does he have the right to have that privacy when he's abused my trust several times?
I don't want to break up with him as I do genuinely love him but it had a huge impact on my confidence and self esteem and he doesn't realize. Every time he does it he says "it's a joke" but I don't find it at all funny. 
Is it too much that I want to look at what he's saying to other girls? 
Is it possible to ever regain that trust?
<bot>: is it possible to trust my boyfriend again? Does he deserve my trust and am I being too controlling and crossing boundaries?
