BP parents treating their children differently

[Guest guest]

I'm curious to see if anyone has experienced what my sister and I have--

I am the oldest of 4 children: 2 sisters, and 2 brothers.

My sister was married a few years ago and her wedding went pretty much

unacknowledged by our Nada. She did not RSVP to her bridal shower, did

not send any gifts or lift a finger....not even ask her how planning

was going, etc. NO support. She showed up the day of the wedding and

that was it. I was married this year and faced the exact same story.

My in-laws must have found my mom to be rude and uncaring. They did so

much for me and I did not even get a " boo " or a card from my parents.

Now...my brother is engaged and will marry next year. He got engaged 1

month after my wedding this year. My nada has done a 180 on us---she

is so excited, looking into their gift registry, paying for the

rehearsal dinner, and even bought the engagement ring for my brother!!

My sister and I are so hurt, confused, and angry.

Has anyone experienced this? All we can " rationalize " about this is

that maybe she is doing this because my brother (who is early 20's)

still lives at home and therefore does whatever she wants him to

do...my sister and I have moved to different states and made careers

for ourselves. Maybe this is why, because we are not around all the

time?
