Why does this happen with every guy I message?

I need advice with my current situation. I’m contacting a few guys wanting something out of and trying to get to know them but they all seem to either lead me on or block me or leave me on seen and sent or ignore me and it’s frustrating because they all seem to be this way but lm really just looking for love and wanting a connection with someone and l just end up being hurt in the end
