My interpretation of Chicago's popular song "Hard to say I am sorry"

"Hard to say I am sorry" is the one of the most popular songs of Chicago.

This song was released in 1982 and charted at the top in US. Billboard.

I used to listen to this song since then but recently, I have just found that the general interpretation of this song has been completely different from what I though for a long time.

Generally, this song is regarded as the song describing the broken heart of the young guy whose girl friend broke up the relationship with him.

See the below lyrics of this song.

=======================

Everybody needs a little time away

I heard her say

From each other

Even lovers need a holiday

Far away from each other

Hold me now

It's hard for me to say I'm sorry

I just want you to stay

After all that we've been through

I will make it up to you

I promise to

And after all that's been said and done

You're just a part of me I can't let go

Couldn't stand to be kept away

Just for the day

From your body

Wouldn't want to be swept away

Far away from the one that I love

Hold me now

It's hard for me to say I'm sorry

I just want you to know

Hold me now

I really want to tell you I'm...

==========================

I used to think this is the song which describes the sadness of the elderly guy whose wife recently passed away.

I am so wondering why nobody has interpretated this song from this perspective.

My interpretation is wrong ????
