Search Results: text instead of phone

I'm dating a girl. Well it could be better between us.

One of our problems or my problem is that it takes hours for her to reply my texts. 4-5 hours, many times over 8 hours.

It wouldn't be a problem if she did this to everyone. But see can reply others really quickly. She can even hold her phone in her hand so she can reply quickly. Even when she is with me, that's how I know. We are working at the same job, and at the coffee breaks she writing on her phone almost all the time.
I can say to her she can reply my text now, while she is still writing. But she say she will reply me later, but she does not.

When she reply my texts it take hours (at least 4-8). Many times no reply at all.

I tried talk to her about this. But she say she is bussy. I said no one is so bussy for 4-5 hours and you can reply others really quickly. But she said it's not true. But I have seen she reply others really quickly.

It's like she is not even curious about what I have to say.

One time when we were watching a movie at my place. The movie was her choice. But after just a few minutes she started to write with a guy in 1 hour. I said to her many times watch the movie and hang out with me. But she said she already have seen the movie. I said it was you who choosed the movie.
I asked her to leave my place and go to this guy's place instead. Because she talked to him on internet almost all the time instead of having a movie night with me. But she said she wanted to be with me. I said you are not with me. You only talking to this guy.

I don't know what to do. It's like she doesn't want to talk with me.
