So me and my oh have been together 3 years...hes admitted to a dodgy past with girls but claims I am the one 
Lately Ive been more aware of his phone usage and in particular his whatsapp usage. So the past few days everytime I left the room I went on whatsapp and nearly everytime he was online...and if I walked in the room he would put his phone down. So I asked him about it...I asked to see his fo e and he point blanked refused...I told him to get out so he did...came back in after 10 mins threw the fone on the floor and said here check it....I didnt bother cause I knew he woyld have deleted everything....which he admitted he had done. Anyway I kicked him out and he was adament he hadent done anything but didnt want me to see his fo e cause he had been 'planning his proposal' to me...that he had a group set up on whatsapp with his mates helping him...he had nothing to prove this as he had deleted it so the surprise wouldnt be ruined. He said the groyp got deleted off his mates fone too.....sooooo I already deep down know what the answer is but could there be an ounce of truth in this??
