I’d probably go against the grain here…
Obviously you have ‘trauma dumping’ and then you have genuine human bonding. I’d say in any relationship of any sort, after a short while, it’s normal to allow each other to really open up and talk about it if they’re feeling down, or whatever they’re feeling. It’s more like ‘another human being is looking to connect with you at a deeper level, why would you turn them away’?
I think it’s a big problem in our society that people can’t open up to others IRL.
We wouldn’t need therapists to the extent that they’re being used now if we had more genuine connections in our lives. I do think it’s a partner/ friend/ family member’s job to be a good listener when the occasion arises, and it doesn’t need to be a years-established relationship to rise to the occasion.
I should know because I have had men I barely know staying on the phone to me for an hour asking for advice, or men coming to my office regularly telling me about things they’re struggling with and saying they can’t open up to partner/ family/ male friends.
I would 100% want a partner/ future partner choose me as the outlet to talk to in these circumstances. Allows you to get to know him on a deeper level/ his true self and make a more informed decision.
I feel like I can’t even develop any feelings for a guy until they do, and until I feel I can open up to them.
HOWEVER I’d be conscious about the ‘feeling down’. It’s not easy being with someone with a genuine mental health issue. Everyone feels down sometimes but perhaps just gauge the extent and reasons.
I’d also consider how much you actually like him. If you don’t see him in your life longer-term then perhaps closing that door early rather than leading on is the right way.
