Hi, hope you r doing good buddy.
See liking someone is not bad but don't come to a conclusion that she is the perfect match for you. I have no clue about your age but you seem young. So, at this age you like everything, you get attracted very easily towards someone. It happens with everyone you r not the only one. As you said you were a " shy person " and recently only you came out of your comfort zone and started talking to girls, they seem interesting to you. As you are polite, humble and doing good in academics may be they want to be your good friend so don't ruin your friendship. (Girls want to befriend someone who can make them feel safe)
See at this age whether it's a boy or a girl,they get attracted very easily towards each other, they have an urge to be in a relationship(to have a bf or a gf) ,get committed.It happens with everyone at this age. So, sometimes girls might take an initiative also.Finding your perfect match or your right person is not that easy you need to consider so many aspects ,as u need to sail in the same boat.
Generally what happens if 2 people are attracted and have feelings for each other they enter into a relationship, THEN they get to know each other they agree on few things nd disagree on few things, if there are more differences nd disagreements they breakup. This happens if you get into a relationship without knowing each other.
From your msgs you also seem fragile and sensitive ,you need to think twice before getting into a relationship becoz you might not handle yourself if go through heartbreaks or breakups nd I DON'T WANT u to go through all that stuff. Even if a girl approaches you or before you approaching someone you need to consider your future, your goals, your passion nd whether you can focus on your studies with such distractions at this point of time.
Even in your future if u truly have feelings for someone nd love them try to know abt each other before getting into relationship, know about ur likes nd dislikes, your goals, your passion, your dreams etc. You need to be on the same page on many aspects, you need to think about each other, you both need to compromise nd adjust .When you r truly in love u do all the above unknowingly, you don't mind each others flaws, you just love no matter how they r nd who they r, you love everything about them.THINK BEFORE YOU DO ANYTHING.
I would suggest you to FOCUS ON YOUR STUDIES. DON'T GET DISTRACTED. When it's time for the right person to come into your life they will come and at that time you won't get distracted, u worry for nothing, things go smoothly in your life. Wait until that magic happens.
THERE ARE ALWAYS DISTRACTIONS ,IF YOU ALLOW THEM. DON'T GET DISTRACTED BY WHAT HAS NOTHING TO DO WITH YOUR GOALS. STARVE YOUR DISTRACTIONS , FEED YOUR FOCUS.
I sense that you have a very bright future. I wish you all the best buddy. Enjoy your life to the fullest. Spend time with friends ,family n have beautiful memories which u can cherish. Go on adventurous trips, visit new places, work hard to get everything you want, explore your life, make new friends( can be girls) .You can have girls as your best friends also. Have a wonderful life kya abhi se is pyaar ke chakkar mein pade ho, zindagi mein abhi se kya rona dona, heart breaks, break ups. KYA YAAR ABHI SE KYU. There is much more to explore . JIYO JEE BAR KE.
TAKE CARE BUDDY.
