the first issue is about the money for the university few days or weeks after she was too demanding and easily became insensitive... isn't it because you didn't give what she wants? if you have given her favor do you think she wont just react that way? yes she is childish but sometimes a university student can be very mature esp if she undergoes difficulties in life. I could see that your gf is a working student usually working students are the most mature young people here in PI. You could just end up into saying I need to think for this relationship but don't you also thought of understanding him because she might be undergoing difficulties, you can tell that because u have met her here, having arguments sometimes would be a better way to get to know each other I have proven that to my husband we have sometimes petty arguments but I tell you from there we become more mature and see our weak points, or consider your age gap, language barriers. We Filipinos knows English (of course not everybody) but it doesn't mean we could have the same level as the native speakers do (English men) How can you establish a relationship if you would easily give up? maybe its just a matter of how to deal with different culture and background. You like other race so be prepared

teach her how to be mature, to be sensitive rather than being tactless Or when things wont really work out with you and her next time try not to get a college level, lol at least somebody who has a career or whoever they are as long as you feel she is the one, fight for it!
