You know...before I got really into this show, I read that in her bio (6 yr relationship)...and my husband and I were joking about it....how could you have a bad track record if you only had ONE relationship. However, in an interview I read somewhere a bit later, Lisa said it was an off and on relationship for six years, so I take it that she did date others during that time and that was not the only relationship she had.I agree with you that it is more inexperience than bad judge of character....she has seemed to fall for some pretty bad lines during this show. Someone else phrased it very well on this board (Swami, I think) by referring to it as a gullible innocence.
