Yes I agree, both have different loving styles.Both also need to be boss.
If you gave what you could, she will definitely appreciate it, if not now, then in the long run.
Basically what she wants is romantic gestures. It's not easy to please Libra - alot is too much, a little is too little. It's hard to find a balance.
My experience with Capricorn men : Either the 'strong, silent type', or the terribly sarcastic (apparently it's a 'joke' and they were teasing). The first I never know - because they don't allow themselves to be known; the second wants to be boss in the wrong way. But they were just friends.
I know a Cap-Libra couple - my friend's parents. But the woman was Capricorn, and the Man was Libra.
Whatever it is, if your love was true, she will have fond memories of you. She might come back to you when she realises what she's been missing. Sometimes it takes a few 'experiments' with other lovers to see who they belong with.
