money

I can make you live glamorously,
having wealth and treasure...

I also able to make your life hard,
weep pinning away...

I can make you encircled by people whom you love,
live peacefully and happy...

I also able to make you avoided by people that you love,
alone and chilled...

I can unite couple easily...
though I also able to detach them even if forced...

Who am I?
