It sounds like you wanted him to show you stronger feelings and to beg you to come back to him, not to take the job, and to run off with him forever. Well, that didn’t happen. I would advise you to be grateful that he didn’t lead you on, especially when you were both so fresh to the relationship. I’d say that everything he did was mature, truthful and respectful.
If you decide to give up the job in your home country and return to the foreign country where your now ex-boyfriend lives in the hopes of rekindling the relationship, you need to hold yourself and only yourself accountable for that decision. If you go back, start up again with this guy, and it doesn’t work out between the two of you, don’t blame him for your giving up a good job in your home country. If you want to take the risk, make sure you take full responsibility for that risk.
