A bit of insights:
They get all weird because they see getting your attention as a sort of investment. They take time, effort, dedicate themselves to figuring out how to best build contact with you, and when it doesn’t work out, it naturally leads to frustration. From there, they either close down (minimize losses), or get weird (frantically trying to make it work).
As per hugs and cuddles, masculine culture heavily disincentivizes tender emotions, and they can be seen as a reason for ridicule. Being burnt heavily on that, many men prefer to be very careful about communicating such needs.
Oh, many men are jealous when women they like hang out a lot with other women and enjoy their time. Modern culture made it look like women may form a special form of deep connection men can never reach, while simultaneously making men feel isolated overall, and some are driven quite crazy over it.
As such, when they get the attention they crave, they don’t feel they can secure it. Thereby, mentioning other women and what they mean to you feels like a threat. This takes a while to unlearn, and is one kind of trauma many men get to experience.
I do not have many personal insights about how men want their friends/partners to be manly, but I may suggest it may come from the same point. Male friendships nowadays are fairly rare, and some folks really just want a bro to hang out with.
