Facebook

Ok so I have been hurt in the past from a previous ex so it's hard to trust anyone. I have been with my fiance for almost 3 years. Every relationship he has been in he has cheated except for his previous relationship and ours. He was very upfront and honest about his past to me. He also was an addict up until about 5 years ago since then he's become a changed man after losing everything and hitting rock bottom. I try not to go through his phone but sometimes I get paranoid for no reason and give in and go through his phone when he's asleep. Last night I went through his Facebook and seen he friend requested 2 girls back in September that he had no mutual friends with. They were on some kind of nature scenery group. One of the girls was born in 1998 and lived in the u.k. but it looked like one of those fake pages that look like porno girls that post nothing but spam and half naked pictures. The other didn't accept his request but her page looked fake too like a supermodel porn girl with half of the pictures not even showing her face. I tripped out and confronted him this morning. Blew it out way bigger than what it really was. He swears up and down that he didn't send them requests he even thinks I am stupid enough to believe that it must have requested them in his pocket. He also sent friend requests to 2 guys around the same time he didn't know which he pointed out he didn't send them requests either. He never messaged either of them or liked their pictures.Should I be mad? Am I being paranoid? He's never lied about anything (up until now) and he's always treated me like a queen. I just don't want to be another girl he screws over and I definitely don't want to be hurt again.
