Need help understanding my situation with ex

My ex (41M) and I (31F) broke up a month ago after being together over a year. He’s going through divorce. We work at the same place. The breakup was amicable but final as I collected all my stuff from his place while he moved. He told me he felt depressed (he had stuggled with depression before we met and recovered), and there were a lot of stressful events in the past couple of months. He has been unhappy in his work and personal life, and not seeing hope in fixing any of the issues between us. I offered solutions but he said he’s too tired, and wanted space to fix himself. He said there’s no guarantee, and didn’t want to keep me. I respected his perspective and as we parted, I cried and he was also sad.

After the breakup I reflected on the relationship, and admittedly I was being toxic closer to the end of it due to work stress. I didn’t realize how bad the situation was, and how much that affected him. We both had communication issues as well since he’s not very open about his needs, and I tend to hide my true emotions and feelings, and resort to anger when stressed. 2 weeks later I apologized for hurting him, and mentioned I am going to therapy to learn to better cope with stress. I told him honestly that he is important to me, and I don’t want to give up. He replied since we see each other at work everyday, being friendly at work will be a good start. We have no contact outside of work.

Since then we have been talking more at work, all work talk nothing really personal but he initiates most of the time. There are good days when we will share an inside joke or two, almost like the old days, and bad ones when we are kind of awkward/no smiles but still talking. Recently he told me about his plans to make some big changes to his work life, and saying maybe he’s going through mid-life crisis because he doesn’t care about work anymore. I don’t know what to say or if I should support his decision because I think it’s a risky idea. On top of that our work is the only line of communication we have, so I’m not sure if he wants to cut contact but doesn’t want to tell me.

I am hoping that we can have a second chance, as the problems we were having are mostly fixable, and I still love and care for him. However, I don’t know what to make out of the current situation, and if he’s feeling the same way I feel. I understand it’s going to take time for us to heal and improve ourselves if we want to try again, but realistically I don’t know how long it may take, or if he’s even interested at all. I’m also scared to ask for fear that I’ll push him away farther. I would appreciate the perspective from an outsider.
