<human>: Give me the gist of the text in a nutshell

Throwaway because he knows my username. I'm (22/F) looking for ways to offer support to my boyfriend (31/M).

First, he currently is employed by a temp agency, and hates the place they sent him to work. I offered ideas, like searching for a new job on his own, but he says due to his field (advertising), he would have to move out into the city because he is unwilling to make the commute out to where most of the ad jobs would be. Oddly enough... I live in the same suburb as him, and make this exact same commute to my own job (so it's not impossible). But he just hates the 45 min-1.5 hour commutes.

Second, he claims he is unable to move out at the moment due to his mother. She was injured during work 2 years ago, and just recently started looking for jobs. I think she needs him around to help with the heavy work. She told us she wants to move to FL to live with her daughter (BF's sister) and her husband after she has saved up enough money and can sell the house... but who knows how long that will take? And it seems more like a fantasy for her at the moment, it's just not realistic.

He just seems so unhappy and negative about all of this, and it's starting to show in his behavior towards me. He'll accuse me of acting differently, or not wanting to spend time around him. I'm offering as much support as I can, I'm trying to be happy and upbeat for the both of us... but I feel like I'm running out of ideas on how to support him. Does anyone have any advice on how I can navigate this situation? I will not consider leaving him.
<bot>: Boyfriend's work/home life starting to take a toll on his outlook/attitude, how do I help him through this?
