I Love Romance

I am just starting a polyamorous relationship and I can't stop focusing on the new person in this relationship. I constantly want to talk to them. He's sick today, but he's more busy than me usually? I can't stop waiting on texts from him and wanting to talk about everything. Anyone know a way to control this? I get like this in a lot of relationships. After time it subsides, but it's driving me crazy. He's like texting not that much since yesterday. Like maybe a couple times a hour? I feel like i should chill, but I'm not sure how.
