How can I stop taking things so personally?

I’ve been told that I take things really personally, and I can see how true it is. My partner sometimes feels worried about speaking up about things because of how upset I might get. For example if he has second thoughts about his car making a trip to see me, he’s worried to say something because he imagines I would be upset and take it really personally.

I think this is something I’ve only recently learned that I do and I’m not really sure where to go to learn how to address it. So I was hoping to see if anyone has had to make progress in this particular area, and looking for advice on how I can learn to be healthier in this particular way.
