Recently, my father had an operation and needed money. When my ex-boyfriend found out, he said he would help me raise money, but he didn't call me. I urged him once, and he said he would promise me.

First of all, you don't need his help at all.

Because he belongs to your ex-boyfriend, he has no obligation to serve you. He's just saying, you don't have to take it seriously.

Now that you are married, you can borrow money from your relatives and friends. Now that you have your current boyfriend, you can ask him for help.

If you ask your ex-boyfriend for help directly, it is unfair to your family, because relatives will also say that you are in trouble and go to outsiders instead of your own. And your current boyfriend will misunderstand your feelings. After all, you two have been separated for so long and are still in contact, so your current boyfriend will leave you.

So I suggest you ask your current boyfriend or your relatives for help.
