please, please help?

me and my boyfriend Luke, have been dating for 2 years (3 years on September 9th) and we got in the worst fight ever, its the biggest fight we have ever been in. We haven't talkedin a week because of this and I feel like crap. But yesterday he randomly texted me saying "hey you've been on my mind all Tag i just cant stop thinking about you,I Liebe Du Kristel" and at night he still texts me goodnight texts. But we don't text during the Tag like we usually do. I'm just really afraid I'm going to lose him, i Liebe him with my life and I can't let this dumb fight tear us apart. I'm literally like in shock right now and don't know what to do, so my Frage is, is there anything I can do to get us back to the happy couple we were? I don't want to explain what happended, but is there any Guter Rat that can help me put us back together, like arrange to go some where and get us back? I'm sorry that this is kinda confusing but thank Du so much if Du help
