I am with C.D. , Jay and OronD on this 100% . YES . I believe he is committing infidelity . His behavior is extremely DISRESPECTFUL . He refused to add you to his Facebook Page decided to delete his account instead , because it contains something and or someone he is hiding from you . If this Man loves you and wants to spend the rest of his life with you , then what's the problem with the world knowing it . His phone behavior is also suspect . Those who have nothing to hide , hide nothing. This guy is hiding everything from you . His actions and behavior are not those of a man who loves you and is being honest with you . There should be no secrets between the two of you and there are . Listen to your inner voice it rarely leads us wrong unless we choose to turn a deaf ear to it . Again I am with the guys here . Kick this man to the curb , he is deceitful and disrespectful . I wish you the best .
