Never beg someone to be in your life. If you text, call, visit and still get ignored, walk away. It's called 'Self Respect'.
Here is one thing that I have learned after all the years I've been on this earth. When a man is truly interested in you, there will be no need for you to do the pursuing. Men are born to pursue women. Yes, you can pursue a man if you want to, but in most cases that's just an obvious sign that he's not into you. It's not natural for a man to sit back and let the woman do all the work. For a man who claims to like you to sit back and allow you to do all of the calling, texting, dating arrangements, talks about the future etc., it's pretty obvious where you stand in that man's life. When a man really wants you, you won't have to chase after him like he's some celebrity who barely has time for a fan. You will be his priority.
Two things you will never have to chase: true friendship and true love.
