I don't know anything more about your relationship then you are revealing here, but it seems to me that:
- you should voice your wish to move in with them (they already asked you not that long time ago, what is keeping you?)...and order a moving van once they confirm that they do, indeed, still want you there
- you should voice your wish to take part in the child's future - and also be specific about how you want that to happen, and ask for their visions of the future)
- you may reveal that you desire to be reassured that you are (going to become) an equal partner in any decition making that is going to take place. Do you want an angagement ring? a ceremony? love poems?
- alle the practical details, from who will pay the bills to who will do the housework to who will stay up at night when the baby cries, will need to be adressed.
