Sorry for the delay with the update: I'm going to read through all the new posts (but suspect I know what they're going to say!)
DP and I had dinner on Friday, I had printed out all the posts on here and read them through with him.
No argument, no anger ... he seemed to take it all on board and it opened his eyes to a lot of issues that he had previously not thought about i.e. how that situation would affect me financially and legally.
I told him (again) that I would be willing to make buying a property my priority, as long as it was with him, as an equal. We then decided to 'have a think' about it. I felt a lot better though, because it seemed he had really internalised what the thread had said, and realised that it wasn't be being irrational.
Last night I brought it up again, told him that I needed him to make a firm decision, and ... he found it very difficult. He keeps saying, "I love you, and I want to live with you" and then qualifying it with a worry about finances, or telling his parents.
In the end I just switched off, really. He's 26, and if he can't either a) listen to what his parents have to say, horrid as it will be, and stick to his guns or b) manage to extricate himself from a nasty conversation then I really can't rely on him to ... be reliable! I want to believe him when he says he loves me and wants to live with me (I do believe he WANTS, I just don't believe he will actually DO it)
Having read this thread over and over, I've realised that if DP is unable to say that it IS his decision to live with me, and make that known to his parents properly, then I'll have to make my own arrangements. I told him that this morning. That I would try to get my own place, but that he would still be welcome to come for scans etc. It would though, I think, mean the end of our relationship. I'm not willing to keep sleeping with the father of my baby, who was unable to stick by me.
So ... yes, that's the situation. This thread did help, and brought up a lot of things that we needed to discuss. Now, it's just about him being able to be an adult. His parents won't treat him like an adult, or accept his decision without a big fight (though really, they should) so it's up to him.
I've given him a couple of days to speak to them, but in the meantine I'm going to start looking at studio places, and talking to Gingerbread etc. I've realised that if I 'let' him, he'll procrastinate over the issue for a loooong time and I'm not willing to deal with that at the moment.
