This happened to me a few years ago, I didn't even notice we were growing apart until the person suddenly just left, started seeming annoyed everytime I said anything to her, then would instantly get excited as soon as one of her new friends started talking to her, even though I'd been there for her every time she needed me. I'm still not over it, I guess.
Stop getting involved in relationships for the wrong reasons. – Relationships must be chosen wisely. It’s better to be alone than to be in bad company. There’s no need to rush. If something is meant to be, it will happen – in the right time, with the right person, and for the best reason. Fall in love when you’re ready, not when you’re lonely. - via: http://www.marcandangel.com/2011/12/11/30-things-to-stop-doing-to-yourself/
Silence is sometimes zen @ times it's meant to teach you something Silent treatment it's like saying I've dealt with so much with you that now there is little to say so just absorb my silence to understand me better ;) lols or not lol hmpp humpp!
