Why does my sister in law only call or text my husband instead of me?

We just moved back to our hometown. We were away for 20 plus years and only got together once a year.

When we were away I don't remember the communication being an issue. We emailed when we would be in town each year and she emailed us ( I think me? Or I emailed her to coordinate when the family reunion would be) but it was a mass email to family as she hosted.Anyway....it was all pretty general.

We moved home recently and moved in with them temporarily. We eventually found our own place and got settled.

After we moved our of their place (brother in law and sister in law- my husband's brother and his wife) anytime there has been a family gathering/ dinner at their place she only has ever called my husband or texted him, never me and this has been multiple times.

She and I got along great while we were living with them and she is friendly and cordial with me.

Is this odd or am I tripping?
