<human>: Can you condense the text into three sentences or less?

I'm a 23 years old male, dating a 21 years old girl. I've been a player since I was 15 and this is the first time I've been in a real relationship. 

I know nothing about commitment, compromise or sacrifice. I never had to do those and I never got emotionally attached to someone. Now she got me completely head over heels. I'm unprepared, I'm vulnerable and I'm sure as hell I'm going to be disappointed at the end and going to get hurt. I've never experienced this kind of pain before and my friends are warning me that I'm not the kind of person to deal with emotional problems. Now I'm thinking to myself, "how hard can it really be? what's the worst that could happen?"

So I have 2 questions. 

1. How bad does it hurt to be dumped by the person you love?

2. Is it healthy to let yourself get hurt when you know it's inevitable?

Thanks in advance.
<bot>: I fell in love with a girl, I know shit about relationships and I'm going to screw this up like I do with everything, am I going to live?
