First date after breakup

My ex and I broke up last week. I found out he already have a new girlfriend and he's crazy about her. I also found out more stuff, which all stung to hear.

Instead of me moping over him and constantly thinking of him ( he doesn't deserve to live in my head , when he been so cruel, nasty and malicious towards me)

I decided to download a dating app and I'm going out with someone in 2 hours. He's bringing his dog, we're going to get food and go sit by the lake since it's nice out today. I'm excited ,but also nervous.. I haven't been out with someone new in 5 years . I know I'm not rushing for anything serious , just gonna do what's comfortable for me.

Wish me luck please 🥺
