Boy name after loss

Some people may know because I’ve posted in here a couple times but we lost our baby at 16 weeks last July. We knew the gender.. a boy. We are due this July with a boy again. Our son we lost, we had already agreed on a name. That was HIS name. We agreed and it was his in my eyes. But my boyfriend is dead set on using the name again for our new baby boy. I am 110% against this and he just doesn’t understand. How can I get him to understand? I’ve tried everything. He constantly brings it up when we can talk about names. I love the name still of course but I just can’t imagine using the name again. Help. 🙁
