One thing that started out badly for me but ended up being great was a time i was masturbating but had nothing to do it to. i tried to get myself excited but couldn't. as soon as i began to give up, some guy who lives only a few blocks away suddenly smashes through my locked door, unexpectedly rushing into my room and buries his face in between my legs. he starts to "feast" on anything he can find.. and to avoid making any virgins jealous, long story short, we did it in all positions possible :) got eaten out real good that day
Answer:
Ask them a question that is not a yes or no question. Send them something that will most likely get them to do some thinking and send back a thoughtful response. They might be leaving you seen for a number of reasons but I don't know your situation with the person so I can't tell you exactly why but that's what I would do for now.
I would do activities with him/her that they love so that they feel better and they forget about whatever they are feeling bad about.
For example if Ronin loves to go to Mcdonalds, I would go to Mcdonalds
