Yup! My husband did a wonderful job of diminishing my sense of self worth and making me 2nd guess myself.
When I needed to assert myself outside of the household, such as for work for example, I’d lean on my colleagues in order to get ‘sanity checks’ since I wasn’t –> feeling <– like my needs were valid, when in reality they were.
I’ve gotten better about that… still have ‘sanity checks’ from time to time. Even at worst, I’ll go to Mumsnet AIBU for a ‘sanity check’ in order to have a bit more confidence there.
