My girlfriend just got back from a trip, she was gone for over a month and she will be coming home in a few days. Ive talked to her on the phone, and Im very scared it could be the end but I dont know why...I've had this knot in my stomach since we talked and I dont know what to do. I love her with all my heart, and if I lose her it will devastate me beyond belief, I just wanna find some explanation for this feeling that its falling apart around me, without either of us causing it or there really being any reason at all. Please help!
