I've given to gofundme's in limited situations. I wouldn't even think of giving to a gofundme to help someone move. Even if you can save up $1000 it would be better spent NOT moving in with your boyfriend; doesn't sound like he is worth it.
First, why is your fiance making you save $1,000 before you can move in with him? Sounds to me like he was setting an impossible goal for a person with no job or car. You shouldn't be asking a question about a GOFUNDME account, you should be asking one about his reasoning though. If my husband had ever told me that I had to save up $1,000 before I moved in with him we would have never gotten married. Why does he need $1,000 anyway?
Whatever happened to working toward ones goals? Actually earning what you have?
In my opinion, gofundme reinforces the notion of a self entitled generation.
He sounds like a peach.
