<human>: Summarize the given text in a few sentences.

We have only been going out for about a month and a half but we have been friends for about 2 years. I thought everything was going great but about two weeks ago she sent me the we need to talk text. I was not sure what I did but when we talked she wanted to break up because she was convinced I didn't actually like her. I told her that I do and she told me ok that if I did she didn't want to break up. Yesterday we were hanging out and she asked me if I actually liked her. I asked her why she was paranoid about it and started mentioning if I had cheated (I would never do this I have my dream girl). She said I can't do anything to convince her that it's something she has to work on herself. I don't know what to do.
<bot>: girlfriend thinks I don't actually want to go out with her and I don't know how to show her that I do
