There certainly seems like there is deception here, however in order to answer this question properly can you tell me more about your relationship with this man, are you dating or are in a committed relationship?
If you both are supposed to be in a committed relationship then there appears to be something he is not telling you. His behavior certainly sounds suspicious. Often when a partner is not being authentic with us there are often signs of deception, most of the time the other party attempts to rationalize the behavior or simply ignore it. In this case if his behavior is contrary to his words (suggesting a committed relationship but getting mysterious calls, leaving abruptly, etc.) it would warrant further look at whether or not a committed relationship is an option. You cannot have a committed relationship when there are trust issues, as every action and reaction would be questioned either verbally or mentally. Most of the time when we feel there is something going on, most likely it is.
