what would i do?

[guest-ca]

My girlfriend said that she want to take a brake for a month to think over our relationship. We had been together 7 year (on and off). She doesn't want to break-up or call it off. She hoped that one day it'll be better between us. We haven't had any intimacy moment in awhile. We both agreed that it's been weird when we're together for the past three weeks. She very busy at work, spent more than 50 hours a week. She says that's what she want to do and doesn't want the interfere with our relationship... I agree to leave her alone for a while but, i'm having a feel that is she want to be with other people. Is our feelings for each other fadding away. Should I worry and suspect her for doing this? please help me out, thank you!
