My gf(F18) Ghosted me (M16)

I met my girlfriend the 1st of January this year here on reddit. We got together sometime in march. We had our first ”movie date” on the 3rd of April I sent a gift for her bday (July 13th) she sent me one for mine (September 16th) We’ve texted (and sometimes called) almost every day for the past 8 months and now from nowhere at the 9th of December she just.. ”dissapeared”?

She’s never done this before, and its really out of character for her. I’m used to her being busy for like a day or two… but ten? No

The last text I got was ”Ttyl❤️”

She opened mu texts for the first time yesterday (day 9) at 23:40 (no response btw)

I bought gifts for the holidays.. dont rly feel like sending them anymore
