I have two adult sons in their late 20s and who both live nearby and as far as I'm concerned my home is their home, it's where they grew up.
They don't stay long when they visit but pop in most days if they are passing or on their way home from work and will usually only call in for 10/15 minutes which I think is lovely that they do.
My dp moved in about a year ago and is really uncomfortable with them just walking through the front door and would like me to ask them to call first and use the doorbell.
He thinks it's unusual to as he puts it just burst through the front door but I like that they feel they belong here and can come and go as they please.
Is this a red flag? He seems to get on fine with both boys but wants me to treat them like guests in their family home but I do get this is his home too now.
I have refused but it's causing arguments every time they come.
