He broke up with me

Ive been on and off with my babys father for 3 years. Well, he and i broke up recently and this time he says he just cant be in a relationship because he isnt emotional enough. I respected his decision. But i asked him if he would be okay if i moved on, he said he would be hurt. I asked him if he was okay if i even talked to another guy and he said he wouldnt like it and would feel some type of way....calmy i said "well thats emotions..." I guess i dont quite understand what he means idk. Maybe he cant show emotion (he never really has) but idk...i feel like its me
