What should i do? love issues.?

Although you're young, you sound very level headed for your 19 years. Your parents did a good job. But that good job doesn't mean that you have commit your life decisions based upon their desires. You have to live your life the way you want. If you make a mistake, then you must live with it and correct it and learn from the mistake. I the matter of this guy, I will hope that you have many, many talks with him prior to making a full committement with him. I matters of love, walk softly. Get it? Good Luck.
