There was this quote I saw recently," If you fall in love with two person at the same time, choose the second one. Because if you really loved the first one, you would not have fall for second one". I do not know if you really like the girl you flirt, but if you really loved the first girl, you would not have cheated on her by flirting with other girls isn't it? If you really do love her and promise you would never hurt her again, you need prove it to her. Give her gifts like bear and flowers personally as this shows your sincerity and effort to be with her. If she still like you, she will return back to you. If not, be prepared to be hurt by her again. It is your choice.
