Relationship Problems

Hi! So I don’t want to end things with my boyfriend and I really want to work things out, but sometimes it’s hard to communicate. I’ve reached out several times, but he gives short and brief responses. The most I’ve gotten is that he feels depressed lately, but he doesn’t seem to want to talk about it. Again, I don’t want to end this relationship and I care about him so much. Anyone going through something similar or have any ideas on how to get through this? It can be emotionally draining at times to not get effort reciprocated. Thanks!
