Mono made some excellent suggestions in his reply, take them to heart. My biggest suggestion would be to talk to K about this.
I am feeling, rejected, or neglected or something. I am a virgo, I am a toolbag, I do not want to act on my emotions just cuz they are there.
I am not naturally an emotional person, and this is similar to my default position. Over time I have learned that it only works short term however, and not getting what you are feeling out there causes more harm than good.
Keeping it bottled up is dangerous in any relationship.
