I regret sayiing this to him?

So basically this guy who I used to be involved with snapchatted me "whatsup", & I asked him why he even snapchats me... he said "why not"....& I said "because we're not friends"... & he hasn't replied since & I'm starting to regret it...

The only reason why I was rude to him was because he has treated me like complete sh*t. We were never technically in a relationship (because he could never commit, might I add), but there was a time when we might as well have been. We hung out multiple times, he came to my house & met my parents, & I spent the night with him once & basically gave him my virginity... & after I spent the night with him, he went back to his ex gf & didn't talk to me for 4 months.

But, after the 4 months of us not talking, we started talking again & hung out briefly. But then, just like last time, he went back to his ex gf, but this time he completely blocked me on facebook without even having the decency of giving me an explanation. & now, with me still being blocked, he snapchats me out of no where all the time. & it's like... I don't want to tell him off. A part of me still really cares about him even if he is a douche & I still want things to work out with us... but at the same time I think it's beyond the point where I need to start sticking up for myself & having some self respect.

Was I wrong for being rude to him? Do you think he'll ever contact me again because of it?
