Why after adding files to git, they are deleted on the computer?

Question

git

I have a problem after commands like:
git add .
git commit -m "some commit"
git push -u origin master
Files on the computer are overwritten to the state they were in the previous commite, this problem was not there recently, I have been working in a folder for week 3 and now there is such a problem in git everything is added, you have to download the documents again from gita every time.
The folder contains .html, .scss and .js files

Answer 1

Why do you do git push with -u every time ? One is enough, the first time. Then it is enough to do just git push without specifying parameters. I believe this is what causes the branch to rollback to the previous commit of the origin branch.
