At first I really liked her. Other girls he has dated it was purely based on looks and they usually turned out to be horrible to him. My brother is almost 30 and this girl is a year older than I am (I am 22). Which, I realize that 7 years really isnt that much....she acts like an 18 year old. Sometimes I forget that she is technically older than me.

And my brother is a very intellectual person. Very philosophical and likes to have deep, intense conversations sometimes. She just doesn't. He has called me and said that he had to call just to have a serious conversation with me because all he ever gets from her is giggling bubbly-ness(if that's a word).

I feel like they are just so wrong for each other. My brother is very logical, very grounded. If he wants to do something (like move to L.A.) he just up and does it. Whereas she is more of a dreamer. Has all these idealistic ideas and is a total dreamer but never follows through.

The other day she told me that people who work at a shelter have a 'God complex' and that it would be better to vaccinate them and spay them and then just release them. I attempted to have a serious conversation with her (I have worked at a shelter for about 4 years) and all she did was joke. When I asked how would they get the money to pay for all that without having an adoption fees and she made some joke about the presidential budget. And I feel like she is one of those people who say these things to SOUND intelligent but can't back anything up.

You know the people who want to seem like this deep intellectual who is all into politics and current issues but really do it as a facade? I'm sure everyone has met someone fake like this; well that's how she is. They have already broken up a couple times and she has asked him to move in with her even though he has said no. I'm just getting really annoyed with this girl and he is too but wont break it off..........How do I convince him to just listen to himself and end it?
