Guys tend to come up with the stupid excuse that if you dont accept me than there is no reason they should love, talk to or even care about you. That is the most ignorant and foolish thing a guy can do. you should have not give up on the girl if you really like her and never let her go that easily. So what if she has a boyfriend. Just stick with her and be her friend to pour her problems about her relationship. Through that you can promote yourself as a better someone compare to her guy and who knows, without knowing she might fall for you. But if she dont you still can gain another good friend or buddy.                                                                                                                                   But as for girls, never never and never make a first move like getting the guys number. Talk to them is fine but dont and never start asking for the guys number as it is very freaky. And girls should never never never  confese to the guy first. If he really likes you that much than he should do it. I know it seems old fashioned but the percentage of relationship failure for that is 99%. So basically there is only 1% you will not end up in a broken heart. So you do the math. Even if you are in a relationship, avoid sacrificing much to the guy because all guys tend to make huge mistakes. It is fine to forgive him once in a while but if he is the one who cause you tears everytime than just end it. It might hurt a lot at first and it is very hard but its better to just end it because the pain will go away although at first it tremendously hurt.                                                                                                                                                                             But teenage of cause its better to not be in a relationship. Even if you do be sure its a clean one. (get what i mean). Love can be shown in so many ways but it is not neccesary to be shown through love. There is so many ways. Through friends or those 'siblings' relationship because it is very true that all this loves last so much longer than being in a relationship. You can get into a relationship when you are in college and preferably in workforce. When you are more assure with your feelings and others and when you start thinking maturedly. But if your current relationship is bringing positive energy to your life so it is no harm and it is great for you. But just dont put your hopes up too high as you might end with a broken heart.
