<human>: Can you provide a brief rundown of the text in within 3 sentences?

I have been seeing this girl for about just over a month now and been dating her for a few weeks. I'm not very good with people and emotions isn't my strong point were as her's is. I usually spend almost all of my time time if I was single like her so It's hard for me to open up.

I don't want to bring her down which is another reason I don't show emotions except being happy. I can't seem to open up as well usually I would over-think everything and anything but I just enjoy being with her and don't spend time thinking about other things around her. I didn't think it was too bad until she said she's scared in case I never love her.
<bot>: Can't open up and show emotions to girlfriend. How do I open up more and tell her what I'm thinking and show more emotions.
