How would you react?

If someone ignores you even after you have put a lot of time, work, efforts into building something which is owned by both.

For how much time,
would you try to understand their point of view, and ignore everything just because you know they are going through tough time, but ofcourse they can decide whether to be in it or not.
and in other case
when you are going through rough time, and their same same scene over constant neglection raises a question does i even matter? creates a more tough situation for you
what would you then?

Since start i have know. one thing.
To solve a matter

you need to
either open up and discuss everything.
or
just take a decision and take action upon it.

and if you are really trying to communicate but still you are being ignored, then what to do.

Looks like there is nothing to do.

But how can that be....

so, here you go again,

How would you react?
What would you do?
