Do I have a right to be upset?

So…there are a couple scenarios that have upset me, and I don’t know if I’m being overly sensitive.
1. My boyfriend came over and said hi and hugged everyone but ignored me. He loves me and my family, so I don't know why I feel hurt.
2. He invited my to our friends house to hangout one night, but forgot to mention that that they have a hot tub and everyone’s using it after. I didn’t bring one, and ended up sitting out while everyone (including my boyfriend) went out to use it for a few hours after dinner. I felt sad and alone.
Are these things worth being upset about and bringing up with him?
