I actually agree with all of your post.I said in another thread that she seems bitter and i think it looks like she's been hurt either recently or by somebody she loved deeply.It has happened to us all.When it happened to me for the first time i was young(around 18) and i did the typical lad thing of not really getting too attached to anyone and playing the field quite alot until i was around 26 when i found the woman i wanted to be with and now have a family with 7 years later.We all handle things differently and sorry to use this word but Sarah seems quite vulnerable and has her guard up.I don't think she's a bad person imo.She just needs to find the right person who may or may not have money in the end.
