Boyfriend's online behaviour
I've been with my boyfriend for a year and we met through the dating site. Our relationship is ful of mistrust and I don't know what exactly is he doing. We both deleted our profiles as we decided to be exclusive. But one day I saw emails while he was checking his mail from pages like myspace and many others, including the ones from which he claimed he erased his profiles! So I did a bad thing and I went to check all of that. Strange thing is that he made them just after he deleted the old ones and the new profiles are not under his name and he has no friends or massages. He just goes there them from time to time. What is he doing? Why didn't he just reactivate the old ones and why he's keeping this a secret?
He once told me he checked up for his ex but from using friend's account. So he lied? It must have been his. I don't know why he even told me that.
I don't know what to do because he is not flirting online but seems like he is looking for someone or maybe stalking. I can't ask him that because he would know I checked up on him. Can somebody help me with this?
