HOW?

How is it that she seems to have no sense of attachments at all,
After being in this relationship for so long?

How is it that she craves for the attention of her friends,
More than the one who loves her?

How is it that I feel so bloody terrible inside,
And she doesn't seem to share the same sentiments?

Its days like this when I think about how much fun she's probably having,
Now that she doesn't have me around
Since I've always been giving her the sense of guilt,
I feel absolutely crap about it...
Am I being normal,
Or am I too self-centred and the entire problem lies with me?

Could some kind soul passing by please enlightened me?
Really appreciate some advice...
It'll be better if you're a Christian brother...
Cause' I think I'm being obnoxious, but still feel wronged at the same time...
