My husband backs away whenever I get anything diabetes related out (cannula inserter, cartridge change,etc). I have to force him to do a fingerprick (on me) every 6months or so in order he remembers how to in case of need, and even thats a struggle. I put it down to medical phobia (I have to take him to have his flu jab, he’s petrified of it, and also to his regular asthma checks, where there’s not a needle in sight). He still married me though
