Confused

Last night I asked my boyfriend to borrow his phone because one of my friends had texted me and I just wanted to tell them that I didn't have texts.He told me no and I didn't listen and grabbed it out of my hands, he literally jerked it out of my hands and I was like wth...now I can't use your phone...he saw I was upset and told me he had to put in the number and write out the text, so I told him its best if he sends it too if he wanted to do everything. I don't know what's wrong with him and now he keeps his phone under his pillow so if I reached for it, he'll know and stop me.
