It's too bad that your girlfriend couldn't appreciate all the effort nga nahatag nimo niya. One thing you should remember is, you shouldn't take all the blame sa inyong relationship because I am sure that you had done what you could, and more than anything bisag nagkalisod ka sa money, you still made sure nga maka spend time ka niya and maka hatag ka niya bisag sometimes lisod, and loyal pajud ka niya. Sayang nga mga lain na qualities nimo ang iya gipangita and there she goes trying to go back with her ex who is abroad. A relationship is a two way thing, it does not take one person for it to work, both of you have to communicate and try to work things out. Iyang sayop kai she never really told you about it, and instead diritso siya didto ug contact sa iyang ex, then MU2x dayon. So she had her faults in it, but it doesn't mean that you should bitter or mad about it, in fact just forgive and take this as something as a lesson learned in life. Eventually, you will find that person who appreciates what you can do, who loves you for you and who is willing to work things and compromise. Don't be afraid in the future to open your heart again, I wish you the best in life.
