Should I cut it?

I've always had really long hair. My dad believes women are supposed to have long hair and wouldn't let us cut our hair. When I turned 18 I started getting regular hair cuts usually up to my shoulders which my dad still disapproves of but 🤷‍♀️🤷‍♀️. Now I wanna cut it off like in the picture but I know my dad and my husbands grandparents will throw a fit. Should I do it?

*his grandparents are super religious and his grandma told him he was going to hell for sinning because I got pregnant before we got married and now doesn't count our marriage because my dad is ordained and did it instead of us going to a church.*
