If your question is something like "Did my ex text me because he is favorably interested in me?" I would have to say no. He/Jup does not receive you/Mer well, since Merc is in the sign of Jup's detriment.
If that is not the question, I think you might need to frame a more specific question like, "Did he text me because xxxxx ? [you specify]" and then the chart could answer that question.
