Girlfriend giving me attitude out of nowhere?

So with my girlfriend the last two days were really good we had a lot of fun together, chatted, hanged out then we came home last night it was still fine we were tired so we lied down and she said im going to watch some tiktok and while she was watching it i fell asleep because i had slept only 2 hours that day. Then she woke me up we laughed she mocked me we laughed again. After that she told me that i need to sleep and continued to watch tiktok but i wanted to spend time together so i tried to open some talk about random things then she said i want to watch tiktok by myself i am tired and turned the other way in bed. Since that she was cold to me i asked whats wrong she said nothing then i said something is wrong she answered no then started to ignore my talking. This morning i thought it is solved it was just tiredness but she was still cold she was going to meet a girlfriend of hers outside and i thought of getting her heart by cleaning and tidying the whole house but the girl that she is going to meet said that let’s meet at your house then i said then let me leave and you two talk comfortably she was ok. After that she got angry to another thing and before i left i said we are going to talk today right? She said no i don’t want to i asked what did i do she said nothing. And told me to leave. My mind is eating itself and i really care so much about her so i need to solve this today right now i am in a cafe near her house im going to wait a few hours for her friends to leave then go and try to talk and i wanted to take some advices from here too.
