Any advice for getting over a guy?

Hello all! So over the past few weeks I was talking to this guy. We would talk all day and be honestly did seem interested in me, and I felt really special because I’ve never had something like that before. I felt like we were such a good match and blah blah blah. Anyways turns out this boy was just leading me on and was flirting with multiple other girls on the side :). So I kind of just cut him off this week and we haven’t talked since. Here’s the thing- I know he’s toxic and I think I’m happy with the decision I made to stop talking to him, but theres still that part of me that has feelings for him. I just want him to stop living rent free in my head, and I want to move on to bigger and better things. Does anyone have any advice on moving on? Thank you!
