My sister is very successful, intelligent, attractive, has her own house and has a full life but has not been lucky with relationships - she has never had a serious partner and she is 35.
Recently she has got a boyfriend who is a plumber, has no assets and has a 6 year old son who lives with him half the time. They met at the gym so they do have something in common.
Now she says he is planning to move into her house - he is going to pay just half the bills. I've met him and he is attractive and charming but to me they seem completely unsuited - I think she could do far better. He is twice divorced but she doesn't really seem to know him, she's only met his son twice and I wonder if he is taking advantage of her naïveté. She says they talk about marrying and having a child.
I have wanted to see her settled down for a long time but worry she is making a mistake - should I say anything to her or just let things unfold? Am I being overly concerned or would this ring alarms for anyone? I don't know any couples who are opposites and I married my first boyfriend from university so perhaps I'm being unfair/ overly judgemental? Incidentally she is not telling our parents about him moving in so I can't discuss it with them.
