I find my boyfriend’s jokes hurtful. Am I being too sensitive?

Here are some examples:
I told him my friend’s dog passed away. He joked eff the dog.
I told him my therapist said I was funny. He joked the therapist thinks I’m a joke.
I said I’m on a diet and lost weight. He joked it’s just water bc I made no effort to lose weight.
I said my job is hard. He joked I’m just a disposable piece of society now that I work.
I showed him my drawing. He said “… what’s that?” as a joke.
I started watching a show. He immediately told me the ending was ass.

What do you think?
