Boundaries not respected

[Daisymon]

I had to put boundaries in place recently as some people kept bombarding me with their negative problems but not asking how I am. They only contact me to complain. I am leaving it about 24 hours to reply but some are impatient and sending another message even though I have not read the last one.

I have regained lots of time for me and my hobbies. Is there any way I can stop them from crossing boundaries still? I should not have to be at their beck and call all the time. They all have a bad habit of messaging at 11pm to 1am and I want to get to bed early.

Ignore it. Archive the WhatsApp so it doesn't disturb you. It's annoying.

If you have an iPhone set the do not disturb between 8 p.m. and 7 am that's what I do

Mute chats, set do-not-disturn on your phone after bedtime.

Boudaries are your approach to people behaving badly.
You can't control what other people do, you can control how you respond to them. There lies your strenght.

I assume you can’t use Do Not Disturb as you want some people to be able to contact you if there is an emergency.

Tell those who contact you late to stop doing so after x o/clock and if they don’t you’ll put them on block till the morning.

Those who are impatient and won’t wait for your reply to their first text- just mute them.

But I’d be inclined to first ask all of them, calmly and curiously, why they do what they do. Making it clear you find it peculiar as much as annoying. They will then have to actually say that they feel entitled to your attention whenever they feel like it regardless of what you are doing and how inconvenient it is for you.

You can state your boundaries but you can't force people to respect them. IME, they are not taking responsibility for their actions and that's a red flag; people who push at your boundaries are sometimes looking for a reason to have a tantrum and present themselves as the victim of your unreasonable behaviour.
State your boundaries again, and fingers crossed for a good outcome..
