My bf of 2 years will turn the phone enough to where I can't see his screen when I am next to him or behind him, like I'll sit in the chair while he lays on the couch facing the TV. He doesn't do it everytime he gets on his. Like checking his sports or Facebook etc but texts he barely checks when close to me, and something else but I have no clue what. I love him and really don't want him to be hiding something from me or worse any type of cheating. We can't really afford to buy anything out of budget right now. I just need advise but I dont think it will be much different then what I already suspect.
