With my nesting partner we use our phones in front of each other unless we are doing an activity together.

When hubs and his ex would hang out and I would hang out with ex's husband (my partner) my partner would constantly be blowing up their spouses phone and it really made hanging out annoying for my husband and I. Then when we would hang out in a quad they would be on their phones and ignore husband and I.

I brought this up once to my ex and he got so upset about it he ghosted me, after being together for over a year.

Of course please answer your phone in an emergency. Or if I have to walk away for a few minutes to bathroom, kids or something else, sure check your FB or whatever. But if we're hanging out together don't be using your phone please.

My sister will use her phone when hanging out with me and it drives me crazy. She's not even showing me funny stuff while she uses it lol.
