I believe the uncertainty with his job is one thing holding H back from recommiting to our M.
I can see this being the case Addie, he may not know what life holds in front of him career wise and this could also be weighing heavily on his mind. This is a stressful situation for anyone changing jobs. My guess is that once he does get a job he will be able to put more focus on the M as he is fighting both of these stressful situations right now.
