4 year old just heard us arguing.

Husband and I are having a really hard time and trying to come back from his emotional affair.

4 a.m. we are arguing and I though quiet enough for kids to not hear. As I went upstairs, my 4 year old (the oldest) was at the top of the stairs crying asking why we are fighting

I’m fucking devastated. Will she remember this? Is 4 still too young to remember these things when she’s older?

Devastated. Please no people coming on here to bash me I will not read your comment. I already feel like shit. Please just give me some insight on how to help her feel better and to let this not affect her mental.
