My sister (who I've been very close to) has an important event coming up. Since she's been pregnant she hasn't asked me once how I am, not asked anything about me for months. We've seen each other a few times, so contact is through texts.
Without sounding like I'm jealous (I'm not by the way), how can I bring it up? I feel a bit resentful and unbothered about her event and I don't want to be.
