she either really means it or she is cheating on you or planning on moving on. sorry :(
It probably means that she is enjoying the time that she has to herself.
Coming from a girl it means she needs space. She needs "me" time. Give her some space then lightly ask her whats up. There is oviously something wrong when a girl says "i need time to think."
She needs time to realize what her wants, needs, likes, and loves are in her life. what she needs to keep and get rid of. if shes asking for some time to herself,i think you should give it to her, and try not to worry. it will make her think and respect you more knowing you respect that she needs some time.
It means she is either having a hard time in life or needed a excuse to break up with you.
When your girlfriend says she needs to grow up, it means that she believes she needs time and space to mature and develop personally. She may feel that she needs to work on herself and address certain issues before committing fully to the relationship.
By providing her with everything she needs/wants. If she needs your time, your respect, your affection, provide her with those things. If that is still not enough, and if she needs to go to another guy for more, than it is time for a new girlfriend.
It means theres a 99% chance she's dumping you, ok. Sorry I had to break it to you.
Move on.
It is very respectful that she is being honest with you and taking the time to sort out her feelings. All you can do is still be her friend but let her come to you as she needs time - don't be pushy or overbearing.
Give her sometime to think things through she will think you are sweet and kind and then you to will be love birds
It is best to let her be at this point as she needs to sort her feelings out. Move on with your life as you cannot wait for someone that has no guarantee of ever coming back and since she has not even contacted you it sounds as though she was letting you down easy as to not hurt your feelings.
Either she is tired and needs rest or she just wants you outt've her face at the moment.
