My heart is aching.

[Akasaka]

Hello, members,
"My heart is aching." Could this expression mean that the speaker is in love with someone? He cannot stop thinking about someone, and he feels something missing when he thinks of her. What other expressions do you use when you confess such emotions?

Thanks in advance.

If the speaker breaks up with his girlfriend, I would say "His heart is aching".

 

[You little ripper!]

Also, I am suffering from a broken heart.

If the speaker is trying to court a woman, then I guess it'd be
I'm aching for her or I'm yearning for her.
