Is it normal to feel so emotional when next to your SO?

I just love him to pieces. I really cant bear the thought of him ever not being in my life. Hes my world and my biggest fear is losing him. Ive never been so head over heels and im so scared. The longer we spend together, the stronger we grow together as one and i just couldnt be without him. Im always needing to cry when i put my head on his chest. Does anyone else get deep in their feels like this???? 😆
