My IL's remember my birthday, but just don't always include me in family photos.
Of course, the whole "Lets take a family photo!" thing with my MIL ticks me off too. Altough hubby and I have been together 9 yrs and married for 3, I am not family. At BIL's wedding when the photo guy asked for a family photo with hubby's bio-mom we both went up there. She specifically stopped the guy and asked ME to step out of the photo.

MIL and hubby have not spoken in 5 months since that incident.
I'd think you were my SIL writing this, except all of our ILs only speak English.
When DH and I had been married for about 5 years, his sister got married. We were in MIL's living room taking pictures, the photographer asked for all of the kids to get into the picture. I stepped forward and MIL told me emphatically that she only wanted her real children in the photo. It was carefully scripted for the rest of the day that I was in no pictures. I guess they still didn't believe that we'd stay together and they could pretend that I wasn't there.
This was the same SIL who asked me to be in her wedding and then picked a dress that would have made me look like a cow. Now, I've worn every other bridesmaid dress that was selected for me whether I liked it or not. This dress covered less of me than what I wear to bed.

When I bowed out of the wedding, MIL told me that they picked the dress to de-accentuate my breasts. I told her that I'd have preferred that they would have accentuated the positive instead of all the negatives.
FF to last month. DH and I are married almost 15 years now. My SIL to whom I referred in the first sentence has been married to my BIL for 5 years. We were at our neice's christening. The photographer assembled the family on the altar and my SIL and I were literally elbowed out of the picture. No one made any room for us and elbows were flying. Our BIL, who married the other SIL 10 years ago didn't even bother to attempt to get into the picture. While our kids were in the photo, we weren't welcome.
So, what did we do? When everyone was off of the altar, my SIL and I, after being very vocal about being pushed out of the family picture, stepped onto the altar so we could have our picture taken together.

Finally, the photographer, a cousin of my DH and professional photographer, was embarassed into taking a photo of the family again, this time ensuring that all of the ILs were in the picture, too.
When I spoke to my MIL the next day, I told her how hurt we were that we were treated so badly. She pretended to be shocked that we weren't in the first picture, but she got the message. I decided 5 years ago to be direct with her when I like or dislike something. We've gotten along great for the past 5 years because of that. She's on better behavior, usually, because she knows I'll call her out on things. She doesn't like the direct confrontations, as she's more passive aggressive, so this way works out best for all involved.
