So the past 3 instances with women I saw for more than a week have ended abruptly and on bad notes.

My typical route is to explain on the first or second meeting that if they're looking for a boyfriend/serious relationship, they need to "look away from me" (for a multitude of reasons) but that I genuinely enjoy spending time with them. This is usually well-received in the beginning. As a short time progresses--between 1 and 3 weeks--I can notice they're catching serious feelings. Naturally, I explain it again to them and shit blows up in my face. Everything from "you led me on" to "you just used me to fuck me" come out and those aren't my intentions at all.

Am I not making myself clear enough? Is there a certain way I should be wording this? Help.
