Should I ignore women?

Hey there. I've recently decided to ignore women that I happen to be around, or at least act uninterested in them. So, if a woman is talking to me I'll just be like "Yeah, thats great" in a nonchalant sarcastic tone, acting like I don't really care. The main reason I decided to do this is because I've been upfront and acted interested before, and I've been ignored. It always confused me so much, well at least now I can be the one to confuse others. My question is, is this going to backfire on me eventually? I don't want to put women down and make them feel worthless, I just don't want to jump into relationships right away and only be ignored again.
