Been living with DP for 4 years, we moved in together when dd was 9. Back then everything was fine, we all got on and I thought everything was fine. In the last couple of years (since hormones have kicked in) dd and dp haven't got on quite so well, but I've put that down to teenage angst and the fact that dd's been having sporadic contact with her biological father which has been a little bit of a rollercoaster but seems to be settling down into a good arrangement. Dp and dd row a bit, but then I do with her occasionally, and I thought everything was still good, especially as dp was keen (like me) to have a baby together.
Fast forward to now, I'm 4 months pregnant and last night dp was talking about how much he's looking forward to the baby coming and us being a family, but then he sprang the idea on me that dd should go and live with her biological dad because she 'keeps asking to' (she only does as a shock tactic in a row) and then 'they'd be a family and we can be a proper family' (meaning just the two of us and the baby). I was too shocked to even reply, it's not as if dd's dad and dd get on so wonderfully that I'd seriously consider it. Then dp got angry that I wouldn't even think about it and kept asking why I wouldn't because it 'made sense all round'. We ended up arguing about it half the night and this morning but he's gone off to work which kind of ended it (I don't work today).
Don't know what to do, the stuff he was saying really shocked me, he seemed so adamant it would be the best thing all round, I just feel devastated that he doesn't seem to see dd as part of our family and could just 'give her up' like that, I thought he thought we were a family already
