Sure, let me try.
What strikes me about this chart right off the bat (from a traditional point of view) is the extremely early Ascendant. This tells me there is something not quite right about the question; that is is not well thought out, not your true question or intent or that the matter is simply a "0" (zero).
You are right about your own situation in that Jupiter is detrimented in the house of that other person. So, yes, move on to greener isles, please.
They recently were combust, meaning conjoined the Sun which is not a favorable condition and probably describes what happened to them or within them; High stress and fear, inablility to act, blinded. Somethign major happened to him to make this change in plans and it must have been something to do with his beliefs or faith somehow....not sure on that at the moment.
However, now, Mercury is very well placed and feeling quite at home although, not really going anywhere since there are no aspects to or from Mercury. They are basically, void and free-falling or floating about. Odd.
The Moon, the action in the chart, is about to square Mars. This doesn't really signal contact. I am having a hard time seeing contact in this chart but, with the early ASC the matter really is still in such a state of flux that it cannot be directly addressed. I believe things are too raw to be pinned down at the moment.
I know it's not easy but, be easy on yourself and go with the flow for now. Things, obviously, are changeable.
