I met this girl one month and a few weeks ago, before I moved to another country, we exchange our numbers and after that we used to talk like everyday like even past 1am something I don't do even with best friends but I told myself since we could not see each other physically so it was the only way to know each other. She used to text me a picture of her, not nude, of her daily life, so I was getting emotionally attached and planned to come back just to see her. But this past few days she seems colder, She still responds to my text and calls, but she seems more detached and takes more time to respond, before she used to text me first and asked me what I was doing now I feel I'm bothering her I don't know.
I know right now she has a school project she is invested in but before she always had a minute to text me what she was doing. So right now I don't know if it is something I said or she's just losing interest in me or me overthinking. Should I stop texting her for a few days and see if she cares by reaching me first?
