The 3rd

I used to cry & give up..
I nearly went to the wrong way but you, you always show me the right way..
I always chasing you..
wanting to overtake you..
I just wanna talk with you..
I WANTED TO BE WITH YOU..
You changed me..
Your smile saved me..
So I'm not afraid to die protecting you
Because  I ♥ U

You come back to me
after I thought you had to leave me
you come back to me
when I’m with other
I have been thinking you would not wait anymore
when I’m alone, I hope you will accompany me
but it turns out you've been missing
and finally I chose someone who not I love
when I'm in relationship with this person
you were back in my life 
I'm confused,
I'm sorry too quick to take decisions
I'm sorry you always late when want me
when I'm near you, I'm happy, comfortable, nervous
but one that certainly I wanted to be with you
what should I do?
end a relationship with someone who is not really I love and relationships with person who really I love?
or continue it?
or not with anyone?
