If you called that number and got a regular womans message machine he more likely is cheating on you and using the phone sex excuse as a simple less painful out. If the text says i love you and ill see you in the a.m. that is much more serious than he says it is.
If he is cheating on you he is probablly not satisfied with the relationship he has with you which means you two need to sit down and have a long talk, because maybe hes not the only one whos not happy, you could be to and just ignoring the signs or afraid to admit that things arent perfect.
I hope everything works out and you get your happiness back.
