Seeing ex for the first time in months. I'm anxious?

How do I stop feeling anxious to see my beloved ex for the first time in months. We are friends still but I'm finding it hard to get my emotions under control. He's happier and I'm still struggling so we both have different feelings.
He's helping me with a job for reference.
How can I manage my emotions and feelings during the meet?
Thanks ☺️
