放棄左金錢 / 放棄左成績 - A lot of great points have already been made above, so I don't have anything to add

放棄左朋友 - This may possibly imply a couple of things:

1. Other people may have told you that "you can do better" by choosing another gf but you don't care how they feel.  If so, I like this in a way - a lot of the time all of us (including myself) care too much about appearances and much how other people think of us, and forget that we don't live for them and should live our lives the way WE feel.

However, it's also possible that others see some kind of "weakness" or really "bad points" about her that you deny, despite pointing out some evidence to you.  If this is true, could they be right?  For example, do you actually love her a lot more than she loves you, and do you know why?

2.  You spend so much time with your gf that you don't have time for anyone else. It's unhealthy if this is true - for one thing, you can choose your gf but you can't choose your family.  Gf's may come and go but family is forever.  You need to maintain good relations and also care about others in your family, and there will also be times when you'll be grateful for their love and support.
