Girls: they confuse me.

Well, you could start off by listening, see whats going on in her life, if she's feeling okay, and if you can do something to help her. If there's a problem at home offer her to stay at your place tonight, if she's sick tell her you hope she feels better and bring her home if she's really sick and wants to leave or take care of her. Pay attention to her, if you take her back to your house or you go out with friends pay attention to her, not your video game or your friends. Call her in the morning to see what she's doing and if she wants to hang out, and also call her at night just to say good night, it may seem stupid but she'll think its cute. Even if she doesn't answer she'll see your missed call and it will make her happy. And if she tells you to call her, call her, don't forget, if you remember her, she will feel like you actually care and she's something important to you, which is definitely a good thing. So all you need to do is just simple little things and you will show us that you care.

If you want to show your girlfriend that you care about her listen to her and listen to what she needs to be happy in the relationship, she also needs to respect what you want for you both to be happy. the way I learned that my boyfriend cared about me was just the little sweet things he would do out of the blue for no reason. its sweet. and it makes us happy =] well most of us.

I agree with kick277kate that's what kind of happened to me I was having a bad day at school and then this was like trying to make me feel better and then he asked me if I was ok on instant messaging even though it's not a lot I still felt better and happy that he does care and remember.

Listening is good, but its only part of it. Try to make it a two way conversation by giving advice or saying something to show you're not only listening, but processing whatever she's telling you. Its also really nice when guys remember the little details. I've only ever casually mentioned some names of my hometown friends or random things I did one day to my guy..friend..(haha) once or twice but he brought those things up again when we'd talk later. It surprised me that he remembered such trivial things about me, but it was nice to know he cared enough to remember.

One Friday during school, my guy friend asked me what I was doing over the weekend, in which I replied by just talked about a small, silly, problem I was having. Well, Saturday, I get a call from this guy checking up on me, asking how the situation I was having went. We didn't talk for long but it was REALLY nice to know he cared enough just to see how I was doing.
I think just little things like that go a long way. Eventually, we ended up dating, and I DEFINITELY remembered that simple, but thoughtful phone call.

The best thing you can do to ''show'' that you care is to simply listen. Not just hear the words, but really listen and pay attention. Maybe even give her the remote to the tv.

Every girl has different interests or hobbies or something different to say or believe in or overall situation in life is different.

Pay attention to these things and what do you notice about them. Listen to what she says. Then think about what it is that you can say or do, that she'll appreciate. Like if she has a really busy schedule and she doesn't have time to sit down and take a break... bring her a coffee or something small to eat. Maybe near the end of her shift.

Or, like, if she is into art and things like that, make her a birthday/ X-mas card (draw or cut and paste stuff out of magazines).
Or maybe she used to do something like roller blade (or something like that) and she doesn't do it anymore. Surprise her with a date that includes what she used to do.

Also, what are your talents? Use that to your advantage. Is there is something you do that you are pretty good at, that you can use to help show her that you care?

And try not to get stuck into doing one nice thing, after another nice thing, after another nice thing. Make sure that you are doing these things while still being yourself. And keep them spontaneous and on a surprise-type level.

There are a ton of little things that you can do... while keeping it as if, as if you were going to do it anyways (you know, for yourself) and you can make it like you want to include her. These are good too. You know- everything doesn't have to be flowers and candy- although sometimes that may be just what she likes.
