<human>: My bf and i are around each other a lot, we're past the honeymoon phase and can stand the silence together, etc.
We're overall a very happy couple.
Lately, its been a one-sided thing where I'm the only one who shows basic affection (kissing, cuddling, etc) but nothing from his side.

The other night we bickered about this, and I finally confronted about feeling off about it. He explained that he wants to show it but another part of him "doesn't have the desire" to do those things? This apparently affects him as well, but it's hard to understand...
He said he was going to try to change that but I don't want him to force himself to show affection. This hurt me a bit, and left me feeling confused me quite a bit too.

I just need some outside perspective from this.

Can you give me a shortened version of the text?
<bot>: bf said he feels he doesn't have the desire to kiss me or show any affection, but wants to work it out.
