You don't seem like you're looking for a relationship.
If you've made it to the end of the list and are convinced that none of the above apply to you, it's possible women are interested, and assume you are not. You could be a supremely smooth, very datable dude. But if you're inadvertently signaling you're not interested in commitment, no sane, smart woman will pursue you.
Without even realizing it, men drop subtle hints that indicate their interest and readiness in commitment. But, sometimes miscommunication can happen. Signals get crossed. You think you're playing it nonchalant by not putting too much effort in, and she backs off, assuming you're involved with someone else, or just not looking for the same thing she is.
Sometimes, in an attempt to date defensively, you say you're not looking for a relationship or you're not ready for commitment, when in actuality, you are. Get real with yourself about what it is your seeking, and you won't send the kind of mixed signals that scare her off.
