No one here can help you... You're fk'd in the head.
Get yourself squared away with your separation from your husband and then work on yourself with a therapist. You are an abusive mother at this point because it's clear that you are not "all there."
Stop worrying about men for the time being, get yourself into ongoing therapy to help you with your emotional immaturity and do the right thing by your daughter. Stop being so bloody self-absorbed and desperate for male attention. You're in no place mentally to be a good partner to anyone.
Harsh? Yes, but your actions as described in your opening post are as irrational as my post is harsh.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
