What does the song "Only the Lonely" by the Motels mean?

Question

What do these lyrics mean?

We walked the loneliest mile

We smiled without any style

We kiss altogether wrong

No intention

We lied about each others drinks

We lived without each other thinkin'

What anyone would do

Without me and you

It's like I told you

Only the lonely can play

So hold on here we go

Hold on to nothin' we know

I feel so lonely way up here

You mention the time we were together

So long ago, well I don't remember

All I know is that it makes me feel good now

It's like I told you

Only the lonely can play

Only the lonely

Only the lonely can play

[Instrumental Interlude]

Only the lonely

Only the lonely can play

It's like I told you

Only the lonely can play

Only the lonely

Only the lonely can play

Thanks in advance!

The woman character is not in love. She's just having physical fun with a previous lover, in my opinion, although "way up here" may also suggest doing drugs together. She's lonely, but doesn't want to have a serious relationship.

The key lyric is in the middle, where he reminisces "the time we were together, so long ago" and she forgot but it feels good now so she's with him. She shows no intention of committing like he does.
