No contact thoughts

My ex broke up with me after 2 years of being in a relationship. This was almost 2 weeks ago. He said that he thinks we aren’t growing together and think we need to grow individually now. He said he still loves me and hopes one day we can come back together but he can’t put in the effort right now because he’s exhausted right now. Nothing bad happened. No cheating or anything. Just no growth in the relationship. He keeps bread crumbing me. Keeps in contact with texting. Not constant texting. But when something reminds him of me. We work together and live next door to each other. He comes up to me in the gym multiple times during my workout to chat. He treats me the same at work like nothing happened. Even bringing his food over to share. We had a talk yesterday and he stated the same. I just started therapy to figure out myself and grow. I’ve been going to the gym consistently since and keeping myself busy. However, I think it’s to the point where I need to initiate no contact. I can’t let him just keep me around for comfort and need to choose myself. I’m not sure if that means this is over or if we will grow individually and come back together stronger. I really don’t know. I guess I am looking for advice on no contact. How it worked for others. What you learned. I’m genuinely curious so I know what to expect.
