What makes a good girlfriend? Watch
That's literally it for me in terms of behaviour.
Intelligent/loves learning new things
Likes to spend time together but equally time alone/with friends.
Shares interests and takes interest in mine too.
Same values/goals in life
That's mine personally. Everyone is different though..some people hate travelling/some people loathe romance etc etc and some people don't require 'ambition' some don't even care whether their girlfriend is employed or not etc etc.
has drive for success
is decently smart
I can't put into words what my ideal would be.
I guess just someone with good general education, discipline and works well as a team.
