I broke up with my girlfriend yesterday, and my heart ached. I deleted her. I told her mother, because I love her,

What the "prospective" mother-in-law said in the circle of friends can be both superficial and deeper-puns.

A person's heart can hold the whole world, but not one person. This sentence can be understood as an exclamation and does not contain the possibility of irony.

The reason why I say this, first of all, you said in your question that you broke up with your girlfriend, and you also said that you deleted her contact information, and she blocked your contact information. This is what we all do in our relationships. Most relationships between men and women have a little trouble at the slightest sign of trouble, and it is difficult to quarrel and break up. These are also small things.

However, your "quasi-"mother-in-law has a man's heart in a circle of friends, and it is all over the world, but it can't hold a person. It is full. This sentence is somewhat similar to the pun I just said.

Why do you say that:

Simple superficial meaning

Some parents often think of comparing the size of a person's heart with something with large capacity while summing up the failure experience of their children's objects, and so does the "prospective" mother-in-law. If it is simply superficial, this sentence will generally show that men are too narrow-minded, so they will make a little awkward and you will not say anything. That's what it means.

The meaning of shrewdness is profound.

Just now, the simple superficial meaning of this sentence means that we men are narrow-minded and make a little awkward, so you don't say anything. But if there is no other meaning, it is easy to say, at least if it refers to the emotional problems between you, it is likely to show that you are criticizing you, saying that you are narrow-minded, unmanly and responsible.

Of course, your mother is also right. Since you can't be an enemy, be the most familiar stranger.

I hope this helps.
