Just a couple of observations based purely on what you wrote. You might be rushing things with these guys. You may not think you’re rushing, but your vibe may give you away. You may have a natural pace that’s faster than other people. And just a wild guess: are you bringing something to the situation in terms of interest or excitement? Is there something about you that might make a guy lose interest in chasing other women? Whatever it is that makes you special, you need to find a guy who wants that.
