My girlfriend of almost 6 months says she doesn't know if she feels the same way about me anymore. She has been gone for a little bit and we were fine when she first left. Then a few days before she was supposed to come back she started acting different towards me. She says she needs a break from us until she gets back. I text her and I can't even get her to talk, she will answer me with one word answers and when I try to get into things she gets mad and defensive and says she isn't talking about it right now. I love her with all my heart but hearing her say she is questioning us really hurts. I don't know what to do. She is amazing but this caught me off guard because up until this point we have had no problems. What do I do? I don't want to lose her, but I want to go back to how we were before.
