Getting money back I lent ex boyfriend

You only lost £7.4k, this woman lost £40k:

All you can do is put it down to being a lesson learned, albeit an expensive one.

Perhaps you might want to explore why you would hand over such a large amount of money to someone you barely knew for over a year by way of therapy so you don't fall into the same problems later.

If your ex is earning £18.5k salary, he's getting roughly £1.3k after tax every month. And all he can afford to repay you is £60? If you are on good terms with him, have you asked him where his money is going or even to increase his payments to you to say £200 per month by standing order?
