<human>: Can you summarize the given text in a few sentences?

So, as the title says, my boyfriend isn't aware of how he feels about things. When I ask him how he feels about something, the answer is almost always passive or neutral. 

Last night, I asked him if he liked it when I played with his hair or not, and he just said, it was alright. (exact phrasing was that it was somewhere between neutral and okay). I asked him if there was anything I do in our relationship that he likes, and he said he couldn't think of anything then, but that he was sure there was. 

All of this just makes me feel like I don't matter in the least, and like I could be anyone and it wouldn't matter, which hurts a lot because I love so many of the little things he does. I've tried talking to him about it, and I believe he cares, he just literally isn't aware of how he feels about things, and it's impacting how I feel about me/our relationship.
<bot>: My boyfriend is unaware of his thoughts/feelings/emotions, and it makes me feel irrelevant to him as an individual.
