<human>: Can you give me the gist of the text in a nutshell?

My boyfriend and I have been together a few months now and although we got off to a rough start due to some mental health issues, things were going okay. Lately we'd been stressed about finding jobs and bickering about dumb stuff, and it just feels as though he doesn't care about me, or he doesn't know how to communicate that he does. He doesn't compliment me very often, or do anything related to the 5 Love Languages despite taking the tests. We were arguing and I asked him why he doesn't do anything to show he cares, and he said he didn't know. I asked if he wanted to be with me and he says he doesn't know. He says he doesn't know if he has the capacity to care about someone in a relationship, and that he thought he cares but now he doesn't know because I explained to him how he should show he cares and he didn't know it required so much effort. I'm so heartbroken because it feels like he isn't even trying to fix anything or that he cares enough to.
<bot>: Boyfriend doesn't know if he cares/doesn't seem to want to make the effort to. I've never felt more alone.
