Thank you for the points you make, especially dahlen for laying out the situation so succinctly.
At the moment I have suggested we start looking to move in together in Sept/Oct.
He is keen and he does want it to happen now, he isn't pushing me but his current living conditions aren't ideal and he needs to move so this is a factor.
We've had short breaks away but no holiday yet although we have one booked, a week, just the two of us in July.
I have most details of his financial affairs although I haven't asked about the finer details yet, I will before we look to move in together.
We have had a major disagreement, during which he didn't insult me or behave in any way to ring alarm bells and it was resolved well.
We have briefly discussed a financial/domestic split and we are agreed as far as our expectations go.
I know a lot about the breakdown of his marriage, he doesn't blame her and takes responsibility for his part in it.
In his other major serious relationship he ended it because she had two affairs (he says) so he couldn't continue.
I have met the majority of his friends and family (they are spread globally).
world his Mum is very religious in a judgemental way, she is quite a character. He neither shares her beliefs nor her opinions, she can be difficult with all of her children (his DB struggles with this more than he does), DP handles her well.
He gets on well with his sister and her family, he doesn't have a daughter and has a (mostly) good relationship with his ex wife. His best friend is a woman - I like her too.
He doesn't have any problem with women, he is respectful and fair.
But something is still niggling at me and I can't seem to put my finger on it.
