Help getting over a breakup?

Ca

So basically my boyfriend of two years just broke up with me out of the blue. He said he had not been in love with me for the past 6 months and he had to end it now. I am completely mind blown because I never would have known and I feel like such an idiot for that. We rarely ever fought and he talked about the future with me a lot. We even recently drove 27 hours to California and nothing different happened. Needless to say I'm heartbroken and I need help dealing with it. Please send your tips
