Boy Toy! Help!!

Hi everyone.... I've been in a "situationship" (involved in a relationship w/out the title of bf/gf), for about 4 years now; Mainly due to his want to focus on his career and not ready to commit. I'm however at the point now where I'm looking to move on. A lot of people tell me that in order to move on that I have to cut him off/not talk to him. I however, look at moving on as a mindset and a perspective. I obviously will always have feelings for this guy, but I do feel like if another guy is ready to give me what I need, I will happily oblige. Am I the only one who feels that I can move on but still have him in my life until someone else comes along?! Or is that not how it works. I'd really appreciate your responses 🙏🏾
