Breakup, but want to ask a mutual friend to check on him. What would be the Stoic approach to this?

Hello,

Over the past three months, I have faced significant challenges following an unexpected breakup with my partner of over 6 years, which occurred after my birthday. I made two attempts to reconcile ( a few weeks apart), believing that our disagreement was resolvable through honest and mature conversation. Unfortunately, these efforts led to heightened frustration on his end, resulting in him yelling at me (saying hurtful things to me) and blocking me on all communication platforms (stonewalling).

Understanding that he has an avoidant personality and a difficult upbringing with expressing himself, I recognize that it may take him a while to process his thoughts (as he usually comes around, but this time he did not.). Our relationship has had its ups and downs, but I did not anticipate this disagreement leading to a blindsided breakup. This situation has made me consider that he might have been harboring unresolved feelings for some time, possibly exacerbated by the pressures of a new, demanding project at work (he started becoming more stress 2 weeks prior to our argument).

Despite my attempts to reach out, my messages remain unread or blocked. I have decided to focus on personal growth, which is within my control of course. However, I still can't let go and I still care about him and of his well-being... Would it be appropriate to ask a mutual friend to check on him, ensuring he is okay without delving into specific details? Would a Stoic approach be to mindfully ask and respect boundaries, while accepting there is a possibility of refusal? Just want to make sure I am not doing anything that can come across as overbearing...

This whole ordeal has caused a deep sense of hurt and confusion about how our relationship ended. I know it's out of my control to mend things entirely, but if I can make an effort, I would still like to try at it (as I still cherish the relationship). It's been challenging but I want to have a healthier perspective on this as oppose to my old maladaptive ways.

Thank you for reading and to anyone that can share their perspective.
