I was sad today :(

I let my ex go. I told him to not talk to me unless he was single and wanted to give us another chance (that was like yesterday morning or the morning before)...and then this evening, I texted him and sent a facebook message. I've been sad all day. I had to tell him how I felt. I'm confused. I guess it's stupid though. I'm trying to think about me, and focus on myself. I was so upset earlier, I cried, then went for a walk. Then I went to my mama's job...then when I got home, that's when I texted, and I cried some more. And then I went on and talked to God (again), exercised, showered while talking to God (yet again)...and then I let "facebook" know I'm taking a break from social media, and came on here. I'm still kinda emotional, but I feel much better now. I was going to talk about him, but now that I'm better and am not crying, I don't want to mention him and start back up. So I'm leaving it at that....oh, and he didn't respond to anything. I did apologize for texting even though I said not to, so maybe he will still not text until/unless he's single, Idk. Anywho, I decided, every time I get sad, I will do an extra walk, extra cardio, extra stretching, or something weightloss related, so I can focus on something else. Or I will listen to a sermon or talk to God. Or watch a good movie, hang out with friends (once I'm back at school), hang out with family, or something that will shift my off of him. 
And now...I'm about to go talk to God some more :)
