My in-laws say Happy Mother's Day or Happy Birthday and I get a card, but that's it. However, for their own kids, they go all out! Big or lots of expensive gifts, including my husband. And they don't usually call me to say anything, they talk to my husband and ask him to tell me..more for birthdays than other days, but still....
Yesterday my MIL made a comment about what she bought the other DIL in the family for Mother's Day but she didn't get me anything. And she's told me at least twice about things she got "all the girls" for Christmas but that didn't include me. It's odd!
I'm sure she isn't doing it intentionally, but it still hurts my feelings. Especially because my mom is anal about making sure she spends the EXACT amount on each person's gift during the whole year. So my MIL is completely different from what I'm used to.
I'm with you though in that I get along with my in-laws and they are good people. Apparently I'm just not on their radar for gift-giving.
Oh well. I keep telling myself not to worry about it nor let it bother me, but it's hard on those days when it should be different. It's really odd she didn't even wish you a Happy Mother's Day! When you were with her! But what can you do about it? Just know it's odd and wish it was different, but deal with it. (I mean that in the most kind and loving way even though it doesn't sound like it when you read it ;-))
Or if you figure out a better way, I'd love to hear it :-)! I could use some help too, ha!
