Can I wish my ex a happy birthday? How to send it?

Can I wish my ex a happy birthday? Of course you can't bless it. We're already exes, so it basically doesn't matter anymore. Most exes are basically enemies, so how can we bless them? That is to say, blessings are considered malicious and not sincere.

So don’t think too much. An ex is an ex. We should make a clean break and have no contact with each other. But I can’t bless you anymore. If you give blessings at this moment, you are being sentimental and self-righteous, and you will be hot on the face but cold on the bottom.
