advice??

So, last night over text my boyfriend and I got into a fight, it wasn't Long or even intense, I think we were both just upset from other factors. We ended up saying we were calling it quits but, like I said I think it's other factors in our life that stressed us and we took it out on each other. We haven't talked since last night at all, I'm wondering should I message him first? If so what do you think I should say?
