Girl, you don't have to give 100% of your trust in guy. There's silver lining if some guy fraudulent behind you. Only the guy with brain will loyal to you. Why you don't have to give 100% of your trust in guy? This will make you down when you end up with him. Some will give worse effect on your exam performance. But if you're a girl with brain, you'll never let such that stupid thing be a hitch for you to be a success woman in future. I suggest all girls to feel angry rather than wasting your tears and cry for nothing. When you feel angry, you'll think that the guy wants to challenge you. In this situation you have to be like taboo in challenge. Always beware of whoever you keep in touch especially guy that in the other word could be a boyfriend.
