It seems to me that he wants to be st8 but he cannot ignore his natural urges for men. Sooner or later he may come in terms with his sexuality but that should not be your concern at this momnet.
I had a similar experience which did not end well. If you can stay in the safe zone of sexual encounters then it is ok but if you have feelings it is better to take your distance from him. This guy will never accept you as a central part in his life, he does not respect you and he refuses to give you his phone number. You will only be a fringe part of his life and he will come to you only when he will want sex with men.
There are many men out there who would be more open and available for you, don't be disapointed.
