<human>: Before you start thinking that I'm a douche, please let me explain!

I love my girlfriend and I feel beyond blessed to have found such a loving and beautiful person. I'm very concerned lately because some of the things she talk about are getting me annoyed.

I remember that we used to have deep conversations, but now I'm beginning to think that a lot of the things she talk about are either superficial (celebrity news, gossip about friends) or complaints. When I start to talk about things I'm interested in, she would either be not so interested or not believe what I'm saying in a rude manner ("oh really? I don't think that's it"). I really want to feel happy when I talk to her. It bothers me that sometimes I'd rather not talk to her about things on my mind. I know I should talk to her about it but what do I say? Is this a personality problem or does anyone know what's going on?

I know this doesn't seem like a big deal, but since we see each other a lot, we talk a lot and I wish I would be happier during our conversations.

I could really use some advice from you wonderful folks! It would mean the world to me.

Thanks in advance!
