Haha, bro, your only 19 years old just like me! You have recently ended a long term relationship, so its safe to say that you may just be having withdrawals from not having a companion. In fact, don't expect to find that one right away, everything is in God's time, and he will bless you with the "ONE" when he feels you are truly ready. You have your entire life ahead of you, so lets not rush the process. Sounds like something another chatter on here brought up. Kakashi threaded a topic about BF/GF idol worship. To sum it all up, young people nowadays are looking for the person that they think will be compatible for them, and in the process are just plain distracted from what your true needs are. I suggest that you stop being concerned about who that girl will be, don't focus all your attention on it and spread the attention to other parts of your life. Remember that God works in mysterious ways, and most times its when we least expect it. Just Keep your head up!
