Should I text him ?

So I just ended things with my boyfriend on Friday . I'm currently on vacation at Florida . And all I think about is him. I miss him so much . We broke up because we were completely different . Like he only eats organic foods no fast foods or restaurants. He mainly watches documentaries about politics or the world or some crap I don't know about . I mean he is a great guy but what drove me away was our differences and I really wanna text him and tell him how much I miss him and hopefully wanting to get back together . Should I text him first or not. And if we do end up getting back together how can I cope with his differences .? Btw we haven't talked since we broke up .
