The thing is that behaviour is influenced only so much by knowledge. Schools do actually teach on healthy relationships and consent and all of that. But you can arm people with all the information their brains can absorb, yet they will still end up in abusive relationships.
Because these behaviour patterns come from early trauma, what they see modelled in their own families, personality type, and social and economic resources (or lack thereof). Most women in unhealthy relationships know they are unhealthy, but they don’t leave because of low self-worth, the sense of familiarity that abuse brings (just like their childhoods), co-dependency, lack of financial resources, the list goes on.
I work in sexual health and you can talk all day about information on protecting yourself from STIs. But people still go out and have sex without a condom for all sorts of reasons - it’s more fun, they were so high, they were afraid to ask, they were embarrassed to ask, it earns them more money, they thought he loved them, etc.
Behaviour change is very complex. Realistically, a lot of it probably comes down to self-worth, sense of self, assertiveness, confidence more than knowledge.
