My DC aged 19 has asked me for help with a dilemma. Their partner has complained that a mutual friend is "too touchyfeely" with DC. DC agrees that friend does indeed give lingering hugs which feel a bit OTT. Partner wants DC to say something to friend but without saying it's partner who has instigated it. DC feels this would be a bit awkward but doesn't want to make partner feel like DC doesn't care about partner's feelings.
Just to make things more complicated, their was a flirtation between DC and friend at the beginning of uni. DC didn't pursue it, thinking that friend was attached -- but this wasn't the case. Meanwhile DC got together with partner.
Sorry about all the language. I'm trying to avoid naming the sexes/sexuality involved as I want to get unbiased comments.
