Meaning of ものの。 in this sentence


> だから、一緒に行動するなら、この気まずさを少しでもほぐしておきたい。  
>  ここは、俺が大人になるとこだよなと思い、歩み寄ったものの。

What exactly is the use of ものの。 in this sentence? The character had a fight
with his friend and because they need to work together, he says want to clear
up the awkwardness.

> ここは、俺が大人になるとこだよなと思い、歩み寄ったものの。

If I got it right the first part is akin "Here I'll become an adult" like
"I'll act as an adult"

> 歩み寄ったものの。

"Although I tried to compromise"?




Yes, this ものの is "although", and you can find lots of examples
[here](https://jlptsensei.com/learn-japanese-
grammar/%E3%82%82%E3%81%AE%E3%81%AE-monono-meaning/). However, this sentence
is special in that the corresponding main clause has been intentionally left
out, effectively leaving the reader dangling. So it's more like this:

> 歩み寄ったものの。  
>  I tried to compromise, however... (end of the sentence)

The sentence might have been a little easier to understand if there had been
an ellipsis after ものの. Usually, you can expect the corresponding bad
consequence is described in the next sentence.
