i think maybe you're expecting alot, and he may not know exactly what you were expecting so he doesn't know how not to upset you like this. maybe calmly explain to him that you saw him online and was hoping for a message from him instead of accusing him, because that may upset even him and just make the situation more frustrating. i'm sorry that you are having trouble trusting him, maybe he is really busy with his work and everything and he's just a bit astray. best of luck..hugs.
