Right. So I accidentally deleted my texts between my bf and I.. 
This is basically our whole year and a bit of photos and videos, holiday memories that we've sent each other. I was gutted. 
I just asked him if I can send them all through again. He said you want to send 1,700+ photos through!?? I was like yeah why not. 
Let me look.. and he wouldn't. I said why won't you let me, he said because you'll go through it I know what girls are like it's happened before with other girls... 
am I'm thinking like dude, all i wanna do is send our entire memories through to my phone! 
I said well should I be suspicious, and he's all like you really think there's something on here? 
This is coming from the person who took my phone into a bathroom at a nye gathering and went through my texts..
( he found banter texts ) with my guy friend but to me it's harmless, however I can understand why it may not be ok in his eyes.. 
anyway, do you think I should be suspicious? Note that, he went back downstairs and said I can look after he's cooked dinner because his phone is being used as a timer. And I sarcastically said - well I don't wanna look after you've deleted  all the stuff you don't want me to see..
