<human>: Ive been dating my bf (M/28) for 6 months. I know its early, but I have very strong feelings for him, and I am optimistic about our future. Except for one thing. My boyfriend can talk about ANYTHING for hours on end, except his feelings for me. I know 6 months is early, so Im trying not to push it (and I know you cant force it), but I would really like to hear ANY verbal affirmation of his feelings.
I know he likes me because we spend a lot of time together and he has invited me to his family reunion in July and other concerts and events that are a few months into the future. He also is fairly good at being affectionate, which is important to me too. So, the physical affection and the willingness to let me into his life makes me feel guilty for wanting MORE affirmation than the non-verbal cues he has already given. But dammit, I need to hear it! Why is it so hard? Are my expectations unreasonable for the amount of time we've been together? At what point do I say- this is what I need to continue this relationship? 
Also, he gets really defensive anytime I try to bring it up. He says it makes him feel like hes not a good bf or that he isnt doing enough.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My bf of 6 months gets defensive when I try to tell him I need to hear how he feels about me and refuses to say it out loud, even though he gives affection other ways.
