It is not all on you. Yes, maybe you 'forgot' about her and she also could have voiced feeling alone.

It seems you are civil with one another. Is there any possibility to have couples' counselling with your wife? Or concretely make an action plan with your wife e.g. let's do this, plan to go out there, date night then etc. This way your wife sees action vs. words.

It *is* possible to get the relationship back on track, as there seems to be love here.
