The bottom line so far is that Ali's self image is keeping her from opening up to the hot/nice guys. She was really scarred by her past relationships. I can definitely understand because my self esteem took a blow after I got cheated on. It takes a while to shake it off. She is protecting her heart from getting hurt again. She shouldn't have done this show because it's not fair to these great guys who seem ready to settle down. She seems to be into Frank the most (and he is the least attractive IMO). One positive that will come out of this season is that she will see her insecurities and hopefully work on them.
