You can't really screw up these things, you get infinite chances to create your reality. Maybe you should take a break from social media until you feel you're in a position to not pay attention to your current reality. 
As it seems right now you're focusing waaaaaay too much on your current reality. It doesn't matter what he does without you, you're already in the relationship with him and he's going to tell you all about it anyway! Just focus on yourself. I know how it is really wanting to be with someone but unless you're happy with yourself you won't manifest anything. Time is only a number so take time to get over the original breakup, you cannot change that but you can shape your reality now, once you're in a good place focus on the relationship with him, but remember you have to come first! 

I have another question... will this cancel out all my other visualizations??? because I got sad.... Is that how the 25 day challenge works???? I don't know..

Your manifestation will only cancel if you decide you don't want it anymore. I know it's hard but try not to worry! Every day you wake up is another chance to align more with your goal. Time isn't important, distance doesn't matter, obstacles are only important if you place importance on them. Bad days happen, just focus on getting yourself in a good place and then carry on with what you were doing. You've got this!  <3
