Has the ship sailed?

I'm the one that's lost and confused apparently. Yesterday the ex posted that he was lost and confused as his status message on myspace and then today I got on to having one less friend. You guessed right, he deleted me.
He was the big one about is still talking,but was strong on the fact he didnt want a gf right now and didn't want to be tied down. Then when we talked about the other issue that was stressing me out he flipped out on me. I was really upset so I just stopped texting him any after that. Well now he deleted me.
I thought I had for sure moved on after he said what he said last week, but apparently I'm not because this is killing me. What should I do? Just let it go. Say that the ship has sailed, never talk to or text him ever again? Or do I text him and ask him why he deleted me?
i took another one of those things yesterday and got another neg. so I'm assuming I had just stressed myself out so bad with what was going on with him and I was so scared of what might happen that I psyched myself out of having one or I have been known to have cyst in the past, but never any that kept me from having a visit, and then I also thought I might have had a bladder infection or something seeing as how I was peeing a lot then, but I'm not anymore. SORRY TMI!!!!! I KNOW!!!! SO SORRY!!! I just didnt want to leave y'all hanging on that subject.
Maybe I'm even more upset because I haven't talked to the other guy in a few days becuse he's been busy. I mean it's not like we are dating. I dont know. Life sucks right now.
I'm so ready for my last class tomorrow and then my fun week next week!!!
