Why has he left me?
Listen darling, i'm a very honest and open person, you have clearly got yourself into a mess that you need to get out of. The first part you have to realise is 'HE IS GETTING MARRIED' so thats the first reason to 'BACK OFF'. 2nd thing, he said he was thinking about you and gave you his new number, have you heard from him, probably not, will you hear from him, maybe if he comes to england for a holiday and fancies playing away from the wife.
What he told you about liking and loving you before he left, was to keep you in his pocket just in case he comes back to england one day and fancies what i just said above or his marriage goes tits up. Either way 'YOU ARE 2ND CHOICE OR SECOND BEST TO HIM' so forget him and move on or you will find yourself in a world of ****, i can assure you that you don't want that.
I wish you good luck but please please please if your ever going to take a strangers advice, take it now.
Sorry for sounding so harsh and black and white but really you need telling,
