Neither of them treated you well, right? So they have moved on to other women to treat badly. I'd call that a blessing.
Take some time away from men and figure out exactly what you will tolerate in a relationship. Then don't settle for less, and take your time getting to know people or getting involved with them. I'll bet in both these relationships you had red flags very early on. That's when to solve the problems or get out.
*edit to say, that may sound a little preachy...but ask me how I know these things? I've spent too much time thinking "what did I do wrong?"
