Hey man, don't listen to everyone. My beautiful girlfriend broke up with me last week. She left me with no choice. You have no idea how painful is it and believe me, you don't to feel that pain. It takes slowly to build a wall around my heart. Most girls will break up.

You're young and enjoy being single while it last until a right girl will find you. Go to party to have fun.

That's just my advice.

To answer your question, no, if you think you love her then don't tell her yet until she took over your heart. I started to tell my girlfriend I love her after about 1 month and an half.

Take care and be safe.
