Do I Break Up With Gf? Or Not?

You know what you shouldn't relyon anyone to decide on this. This is a relationship between the TWO of you,so settle this between the TWO of you. Why need a third party to tell you what to do,don't you have ur own decision. The gals like you that's why they want you to break with ur gf! You must use ur own eyes to see,use your heart to feel and use your brain to think. If you are really confused on some stuff,just ASK her. You can bring up the issue you are concerning,and pls keep asking her the same time but rephrase the questions because sometimes gals are not that straight forward or will want to put up a brave front and will LIE to you. And sometimes her eyes or actions will betray her. Like for instance if you ask her "do you  love me?" and she said "NO" without looking into ur eyes or back facing you or tearing,then it is OBVIOUS lying.haha
good luck,everything needs communication!

It depends.  What are your priorities and her's.  Do you see each other together in the future?  I mean work it out together and if the best thing is to be friends you didn't lose anything.
