how long should i wait?

so i've been dating this girl for about a year now and I am in love for the first time she is in love with me to she says.

everything was going fine but now she suddenly wants to start spending more time with her friends (all female) meaning less time with me.
this has come at a point where i want to spend more time with her she has become my everything but she tells me she is not ready to become my everything.

what im asking is how long should i wait for her to be ready to become my everything as well?
and how should i cope with this time?

thanks in advance!

There isn't really a deadline , you just have to wait and try to understand what scares her in being your everything ....

Ask her why she is so worried. Maybe she doesn't want you to get too attached in case something happens. In which case she's trying to spare your feelings. Maybe she needs to be more sure of her own feelings first.
Just ask her what she's thinking about the situation and go from there. Good luck.
