I just wanted to say thank you to all of those who commented on my other post about my sibling.

Throwaway for reasons.

So two weeks ago it was my birthday. We have a tradition in our house that no matter what we always go to see the birthday person and wish them HB in person.

My older sibling who I have an on/off relationship with stated that as they have taken their medication they could not come. They didn't tell me this, they relayed it to a family member.

For some context I'll refer to my sibling as M. If M is going through anything **you must drop everything and help**. If you're at work, you gotta leave, if you're ill, you gotta get better and go help.

When it was M's step children's birthday, they demanded that I come and help with decorations and bring a gift. I had had an operation the day before and was feeling very raw. Despite this, I ran like an idiot looking for gifts that the step kids wanted as my original gift "wasn't good enough".

When I did arrive, bearing in mind I worked 30 miles away from them, I got berated for being late and wet (I had ran in the rain) and getting their banister wet.

There are many examples of me having to drop everything to accommodate M.

Fast forward to my birthday. I did get a HB wish by text from them. They had called my folks and asked what we were eating and what cake would they be getting (I didn't know this until a week later).

The assured everyone that they would be here. I get home at 6pm, it gets to about 9.30pm and no one's home. My cousins call and explain their stuck in traffic which I totally understand.

My cousins get in and explain that M won't be coming as they've taken medication and now they have a headache. I then found out they went to see their partner instead. M has no medical conditions and has a very bad case of "One up syndrome". If you're ill, M is halfway through the black plague.

I feel hurt and stupid for expecting anything else. I thought this time they would actually come and change.

AITA for this being the last straw to keep in contact with them?
