Me and my girl have been together a year now. She loves me and I love her but she said she needs me to rekindle the flame. She is the one I know and she knows I'm hers. But we have had some problems recently and she is having doubts. She wants me to make her fall back in love with her prince. I need some romantic ideas to make her fall harder than before. Any ideas are helpful.

She has a misguided notion of love, and it sounds like you could use some help too.
Romantic love must evolve into a different kind of bond, one based on mutual respect, understanding, communication, admiration, and compromise. Romantic moments are nice to keep as special gifts for each other, but in a way are mostly nostalgia and a contrivance to keep a spark going. You do it because it helps, basically. A WOW when she looks good, tell her to twirl around, kiss her neck while she's doing some stupid housework (and take over sometimes), sit her on the couch and put your arms around her and ask her where she sees both of you in 10 years, or to tell you more about her childhood because you wish you were there. I'm not going to write a book for you. If you can't think of 1,000 more little ideas, then start thinking harder.
Couples need to keep letting each other know they are APPRECIATED. She's not your mother and maid and you aren't her bread and butter.
BUT she needs to understand the stages of love too! Try to explain that it's something deep and unspoken, but that you will try to say and show it more, because that's how women are so different from men. She needs to understand you too. THAT is love.

Joy is very right, but couples do tend to fall into a rut of daily routine. Why not take herr out for dinner or make a special romantic dinner at home once a month. But more important it's the little tiny thoughtful things you do throughout the day. Like randomly send her a sweet text, take time out and walk over to her and give her a hug out of the blue for no reason.

Its simple, you let her know with words and actions that she is wanted and appreciated, and if you have been paying attention you would know how she likes to be treated. That's where YOU start, with paying attention, and being attentive. And a heavy dose of sincere.

Do you live together? How old are you both? Do you both work? What are the issues making things so rough? Seduction, and romance start in the mind, not the wallet. These are important factors.

She definitely has some misguided perceptions about love! You know what? It's NOT your job to be her "Prince" and be more romantic and take responsibility for her feelings (and passion). Her doubts (and yours) are normal for any relationship. What brings back spark and passion isn't just the little things... it's how much she is allowing herself to be really vulnerable and open and connected to HERSELF (if she's relying on you to fulfill her she's in for a rude awakening). You can only do your job - which is to value yourself, be honest, be open and do your best.

What is your best and what are those little things? The biggest, heart-opening, love-creating and aphrodisiac quality is LISTENING and just really (totally!) being THERE and present with her. Making her feel loved and valued because you care what's going on with her. It's not about the biggest teddy-bear or diamond. You want to feel loved too -- so give her what you want her to give to you. Ask yourself that and that's your first clue. Open up your heart first. That way, romantic gestures and spontaneous romance will come from a genuine place instead of pressure, "must make you happier! Must be better! Must take responsibility for your passion!" -- that never works for long.

Maybe you should be solving the problems you are having before you kiss her butt... I mean rekindle the flame for her.

All good ideas on the full range of possible ones.
