Why does her mood changes if I’m not talking?

I have this platonic female friend who has a boyfriend and they been dating for 5+ years. Past month or so I noticed when I’m not talking and I’m to myself. She tells me not to talk to or touch her and I stop doing it. Her whole mood changes. She becomes angry and snappy towards me. But as soon as I talk to her or show some type of affection she’s as happy as winning the lottery.

When we last talked about why she was angry. It was because I wasn’t talking to nobody. But then she realized how silly that sounded after I repeated her. She tried to change her reason.

what is the deal with her? Why her mood changes when I don’t talk to her. Any other friend she doesn’t care to talk to them. But with me it’s a different story. I only known her now for 2 years.
