Is this the end of my marriage?

[P17]

An update for today and genuinely asking for some advice as I'm a little lost.

Postal mail came in today. A card from W's mum (I recognised the handwriting on the envelope). I thought that was nice, a xmas card.

Unfortunately it was a condolence card for my mum. With a letter inside.

The anger filled me like you were filling a jug. I briefly skimmed the card and the letter as I couldn't read them for it.

The letter basically said that they were sorry, they liked my mum and my D needs her granny and to give her a big hug.

I had to leave the house right away. I went for a walk on the beach for an hour to calm down.

I am still angry, but I can at least type now.

I have no idea why I got so angry about it all. My mum's death was a private matter for family. Those 'people' didn't bother to contact me when my mum was ill, contact me at any time in the last 4 months including when I told W that my mum had 2 months to live. They haven't contacted me about D or to see how any of us were. And now they think it's okay to write me a letter telling me they are thinking of us and how important a granny is to a little girl.

WTF?!?

Am I missing something here, and I really mean genuinely missing something. In my angry emotional state I could very well be overreacting to this. In fact I know I overreacting but does anybody else see an issue with this?

And to top it all, no mention of their D who decided to walk out on me and her step-D. Yeah, a grannys love is important to a little girl, but did you tell your daughter about how important a step-mum's love is to a little girl? No, clearly not.

What I want from W and her family is to be left alone. The occassional xmas card would be nice but that's it. Nothing more. NOTHING. They are not part of my life so I don't feel they have a role in telling me how important anything is to a little girl. That is MY little girl. Their D abandoned my little girl and her H for OM. Her family have supported her through this - and facilitated it.

ARRGGHH!!

My question, is why do I feel like this after the smallest bit of contact? I AM doing so well. I was feeling great yesterday and then the smallest bit of contact comes in and bang, off I go again.

And do you know what really REALLY hurts after saying all of that? Not even a whisper from W about my mum. No 'sorry' or anything else. What a cold hearted b*tch she is. How she found out, I've yet to discover.

I apologise for my rant. I just need to get this out.
