We all have our moments where things drag us back downhill. Just detach from everything going on around you, do something that is fun, and completely get your mind out of it. Play outside with pets, kids, go for walk, blast music in that ear so your thoughts are muted, go to a movie, do anything that makes you completely forget about time. Sometimes we just need a break from the work and to simply relax, even if it's as simple as reading a book or taking a bath.
What you seek is seeking you. Don't even worry over the reality of what's up. don't overthink, don't create a problem where there is none. If you want him back, it'll happen when you can think happy towards him versus the negative "stay away" vibe that is desperation and need to have him there. When you don't care, but would prefer him back, that's usually what happens. Take signs as the universe confirming to you, "we're working on this for you, go about your day and have fun." Say "thank you Universe," then go about that day knowing it'll happen. And realize that when it takes longer than a few days or weeks? The Universe is making him a better person for you. Because you deserve that. Can't eat that delicious cake before it's ready can we? Or it'll just be a puddle of batter! We want that delicious slice of baked cake that's all warm and perfect.
