It's hard to love when pain is all u've ever felt

I'm torn between 2. My first love, and the guy I talk to every single night b4 I go to bed. I don't know what to do... Both of them each have half my heart, It's just who's willing to fight for the other half, and who I'm willing to give it to.

What am I supposed to do? I have feelings for him but he don't for me. He calls me every nite before he goes to sleep. He acts like he likes me. He refers to me as "the wife" around my best friend and her bf.
