Farage brought us Brexit, the overall divorce bill of which is around 37.2 billion, we will be paying it off until 2065
The Brexit divorce bill is considerably less than our budget contributions would have been until 2065. Your argument as it is, is flawed.
Some figures here put the divorce bill nearer to £30 billion (after deducting £6.7 billion owed to us);

During the transition period in 2020, the UK was still a member of the single market, customs union and EU programmes, so we paid into the EU budget as if we were a member state (£8.9 billion net for 2020 - included in the divorce bill). If we had remained a member of the EU we would have paid that amount anyway and similar amounts (or more) for 2021, 2022, 2023, 2024 and 2025 (over £53 billion 2020 - 2025).
According to This is Money, October 2025, a bit less than £6 billion of the divorce bill remains to be paid, mostly covering pensions to 2065.
(NB We are making other payments to the EU, e.g. for membership of Horizon)
