friends

Good girlfriend would be someone who pays attention to you, cares for you and feels for you. All girls like to be treated good with high regards so definitely you have to be dining out with her, call her often and show her that you care for her by gifts sometimes or maybe public display of affection for her. But true friend or girl friend won't be the one after your money only and interested in just having good time for a while. So do show affection by the ways mentioned above but never ever overdo any of that.

The freind of the good girl was the freind that attention to you :D
