Go with your heart. Express your feelings to your significant other. See what their opinion is. But remember, time apart can be good OR bad for a relationship. Perhaps ask yourself why you think time apart would be good.
Do you feel smothered? Do you feel like you are losing your own identity? Do you feel like you are not able to do the things that YOU want to do? Good luck in whatever you choose, you will do the right thing, just make sure you know what you want.
