What if my girlfriend rarely shows emotion?

I don't know why I'm even seeking advice on this subject, because I don't know if I should need some or not. My Girlfriend is everything I could ask for. I could not ask for a better Girlfriend. She just seems to lack in emotion though. Maybe I am asking for too much. She has more fun, and seems happier when she is with her friends. She'd come over right now If I asked her too. She just seems emotionless sometimes. She left for a cruise with her parents, and I had a friend sneak 24 roses into her house while she was away. She never said one thing about them. She never messages me. Hardly talks to me on her own. Doesn't tell me she loves me on her own. Hardly ever seems like she is happy to be with me. She shows emotion only when I try and show her a lot more than she ever gives me. I do all that I can for her. Also when we're "intimate" she just lays there. Claims she likes it.. but just shows no sign of life the entire time. Like she could be asleep and show more signs of life than this. I love her, and she always tells me that She'd never in her life want to lose me.. She only tries when she thinks I'll leave her. What is going on here? I've almost tried to part ways because of this, but can never do it because she does try to keep me, but that is like the only time she ever shows emotion...can anyone help me?

Alright, in my point of view from what your telling me it seems like shes just playing games with you..
It could be that she wants more from you.. though it looks like you give her a lot..
I think she doesn't message you because she wants you to message her first, and she doesnt talk to you on her own because she wants you to talk to her first, she doesn't tell you that she loves you first because she wants you to say it first..
So she'd feel special, and she wants to feel that shes your first priority in life..
Like you said, she shows a lot of emotion when she feels like shes going to lose you, because she only shows emotion to you because she feels that she needs too, to keep you around because she doesnt want to lose you. Than, when everything is fine she will go back to being "emotionless".
It's not cause she doesnt love you, shes just the girl that likes to play hard to get, though you alreadly have her she just likes being chased for more and more..
I think she hardly seem happy when shes with you, is that she fakes it so you could ask her whats wrong and give her lots of attention.
I think you should let her have a taste of her own doing, and let her chase after you and do what she is doing, it might make her feel bad like shes making you feel but its so she'd learn what shes doin.
When you dont message her, for maybe a couple days she'll miss you and start messaging you.
When you dont tell her you love her, she will eventually say it after a couple hours or so.
And when she askes you about it, tell her about how you feel and that this was all planned to make her feel how you feel.
So um yeah, good luck..

It sounds like she's dating you for other reasons. I'd start playing her game...act aloof, ambivalent. Start hanging out with your friends more, stop texting and calling her every hour. There's nothing as unattractive as a needy man.

If it doesn't work, dump her!! You sound like a sweet, caring, sensitive guy. You deserve a girl who appreciates you!! So get some confidence, sweetie!

She might also be 'emotionally unavailable' ...a more common trait in males. Or she may have had some traumatic experience in the past that numbed her emotions. You're probably just going to have to ask her.

Yeah. I finally had it out with her last night, and she opened up like she never had before. Like I said, she does show emotion, just not all of the time. She told me she was trying, and that she had never loved anyone before. That she didn't know how to act when someone loved her so much, but that she'd do anything to make it better... so we talked it out.. and I think I overreacted about the whole subject. She is the perfect Girl. She spends most all of her timw with me, and she is one of the girls out of many who doesn't cheat. Doesn't lie, or anything. I guess maybe I'm looking for something to be wrong with us because they're isnt..?

I envy you...
