Sometimes I feel like my girlfriend doesn't love me.

There has not been a major change in the way she acts toward me. She's been reserved from the beginning. I thought as time went on she would open up to me. But we have dated for six months, and she has not changed.

It's not what she does, but what she doesn't do that is so painful. She says she loves me, but does not act that way. It drives me crazy sometimes and I don't know what to do. Sometimes I feel that I've been putting all of myself into this relationship and been getting only trickles back.

It's not like she doesn't really love me, but that she's holding it back so that I can't feel it. Her love surfaces now and then, and these brief gasps of air encourage me, for I know that hiding underneath her defense barrier is a person who loves me dearly and desperately as much as I love them. That's why we've stayed together so long. But she shows this side far too rarely, because she's afraid of getting hurt.

What should I do? I've already tactfully confronted her about it, and she said she would make an effort. But I have not seen any change. I don't know what to do, because I can't really keep pressing the issue.
