Punishments that fit the crime

My family always seem to be at war with one another all the time, honestly it's like living on a battle field!

My brother was more less disowned by my family for a couple of reasons. One was compulsive lying and the other reason was that when my dads business was struggling my brother told several lies and pretended to be several customers, one of which had an Autistic daughter who promised to come and see us and me. It was probably the cruelest thing my brother ever did to my family and me and my parents never forgave him, especially my dad.

That was the big one and the others are all petty arguments, you know like my brothers all trying to get each other into trouble. As I stick to and always have stuck to myself luckily I'm never involved in any of it but it can be irritating when I can hear them shouting and arguing.

I sent a two page letter two months ago , I sent a Christmas card twm week ago saying I hope the new year brings forgiveness and reconciliation. 

Two days ago I sent a text. 

I have no response to anything in a year.

I am autistic not them

Assuming the person whose stopped speaking is Autistic, maybe you inadvertently did or said something that made them question whether you still saw them as your friend? Autistics tend to have very narrow definitions of things. eg I have autism my definition of a 'best friend' is that the person would tell me important life events before they told anyone else (or I'd at least be in the 'select few' for that person who was told before it was announced on social media for example).

So if for example if someone who I believed I was heir best friend as I'd been told that in the past , announced some important life event on social media and I realised I hadn't even been included in the people who'd been told before they told everyone else then that would mean to be they no longer saw me as their best friend so I'd disconnect from them. They'd then be treated like an acquaintance or someone who had to be 'tolerated' like a social worker visiting.

Have you reached out to this person recently? sometimes after the heat of a fall out settles it can seem unnecessary or awkward to continue as nothing had happened. maybe this family member simply doesn't know that you want to be in contact, as harsh as it is maybe they simply don't think about you anymore rather than actively avoiding you..? my partners mum stopped speaking to her for 3 years after an argument, until one day my partner asked her for some medical information, then after gradually building on strained conversation they are back to acting like family, the avoidance wasn't through hate or anger it was simply two individuals with loose family values getting on with their own lives..
