@Solene This does not seem like a healthy situation for you. You deserve to know where you stand, and from an outsider's perspective it looks like you are being mistreated and taken advantage of. I am not sure if you are ready to hear the advice many people will have for you... but deep down you must already know that if this man cared for or respected you he would not leave you hanging like this. Crass excuses of being busy with work do not mean you can ignore somebody for two weeks. I suspect he has had his fill of this secret affair for now, and you will only hear from him again when he next needs his ego stroking.
