Should I be dating him

Hello! I've been dating J for a while. It's a LDR relationship. I've been questioning if i should continue my relationship. He is not mean or abusive, he is just really emotionless and has a really hard time showing his love. I keep trying to help him but it always goes back to J saying "you shouldn't expect a lot from me."

But he does show his love sometimes. I love helping people so I'm wondering if I should continue helping or move on. I do see potential in him but I don't want to keep not being loved while I'm giving him all of it in attempt to help. Advice? Thank you.
