ah /: way older then me

and like i never had a problem with my previous bfs checking out other girls as it is human nature but since all this happened
is happening every time he stares at a girl it makes me think back to the comments he says and it really irritates me /:
i have told him why i have a hard time trusting him and all he says is
" have i ever cheated on you ?"
and i say no because he hasnt really .
just does not feel right
