A colleague has become very dependent on me, both emotionally and practically, at work and I'm starting to find it overwhelmingly stifling. How do I withdraw without damaging his mental health?
Situation is that our workplace is pretty toxic at the moment. Both of us have at various times been picked on by bosses and have found some solidarity in this. I'm pretty thick skinned and I will let off steam about it short term but generally am OK at cracking on.
My colleague, who is junior to me but fairly senior within the firm, has started wanting tons of emotional support from me about how to deal with this. He calls on Teams multiple times a day without warning (usually when I'm already on calls, and won't take no for an answer). He emails me on very thin pretexts demanding an urgent response. Or he wants to go for multiple coffees per week, asking for help in dealing with the bosses' most recent unreasonable behaviour.
He has now started asking me to join him at events outside work and to talk about how important our friendship is: I've said no to all of them so far saying I'm busy with work and my DD and don't have much time (which is true). He accepted this for the first two or three but recently he invited me to an evening event, I politely declined at which point he became tearful and said I never made time for him so I then to spend time reassuring him. He's gay so he's definitely not interested in me romantically (and I'm in a settled LTR which he is aware of and he's met my partner) but has come to see me as his emotional support and I just don't want this. I don't dislike him but I find his demands very draining, we're not friends in any meaningful sense of the word and I just don't have time or bandwidth for this sort of entanglement at the moment.
I know I need to draw up some boundaries here and was hoping I would be able to do this by just grey-rocking him outside of work-related stuff but it's clear that I'm going to have to spell this out in some way. I don't want to hurt him and I think his mental health is pretty fragile and he probably needs professional help. He's also mildly autistic and really struggles with communication so I'm worried both about hurting him and also about failing to communicate clearly. I also don't want to leave myself exposed to any accusations or bullying or poor management.
What's the best way to politely say to him that I can't provide him the support he needs?
