Whether you like Bettina or not, or think she'll be Final 1 or not, one thing seems to be clear to me: Of the 3 women we know will be left after next week, Bettina seems the least likely to be ready for a relationship or able to carry a healthy one. It's not just the nervousness or her inability to speak clearly but she just comes across as actually the least relationship-savvy of the bunch, which is ironic considering she only last week seemed to want to lecture the other girls about what it takes to make a relationship work.
I say this (based obviously only on what Fleiss has shown us) because of 1. the vast disconnect between what she says in her PI's vs. how she really acts, whether it's with Brad or the girls and 2. because she just seems so AWKWARD and unsure around Brad. She actually seems the most inexperienced with men, which is not at all what you'd expect from a divorcee.
I mean, she doesn't want to be kissed, but then she does? And when she changes her mind and wants to be kissed, she goes in for a peck on the cheek and looks embarrassed doing it, and then the next time she sees Brad she says, "I want your hands on me." AWKWARD. She blurts out "I love you," backs that up in a PI with saying she really meant it, but then complains only a few days later that her single, only, lone one-on-one date with the man she "loves" was boring. WHAT? She tells Brad that her marriage wasn't one in which she was totally in love (I don't have her exact quote, sorry) following a conversation in which she told the other women that they can't possibly plan to build a life with someone they've only known for a for weeks, but she was with her boyfriend for FOUR years before they got married (and that clearly went down the tubes pretty quickly) ... so I guess you can't know in four years, either, if you're with someone you want to build a life with? I mean, I don't get it. I don't get any of it! These are the disjointed thoughts and actions of a 15-year-old girl who has no idea about falling in love, IMO.
I don't think Bettina is a bad person or anything like that. She has just been shown (whether this is an actual representation or not) to really be the wounded bird type of character who is confused, uncomfortable, frustrated, naive and really needs to have more experience with men, and being HERSELF, COMFORTABLY around men, before she will be ready for an actual relationship with one. I have no doubt that her divorce hurt her, and did a number on her self-esteem and made her question her own identity (been there, done that myself), but I think her hurt is manifesting in ways that suggest it is too soon after her divorce for her to be in a serious relationship again.
A man cannot give Bettina what she needs right now, and she cannot give herself completely to a man. So, Brad MAY pick her as F1, but I think that would be really sad as I don't see the relationship working and it really would not be a good thing for Bettina. If she were my friend, I'd tell her to play the field and go on casual dates and not even THINK about getting serious with a man for awhile -- not until she is stronger and more self-assured and more at peace with who she is.
