If a man is feeling low...?

My boyfriend has been feeling very unhappy with his job situation. He sent me a message yesterday that he feels so unhappy and stressed out. He has been applying for new jobs, after working the whole day. What is the best way to support him? I became very needy of him a couple of weeks ago, crying to him as he has become focused. He said he was sorry but he needed to focus. He said that I don't support him. I have started to give him space and things have improved but he is not as attentive as he used to be?
