To ask him to come to my 4D scan?

[katesmate]

Im halfway through an unplanned pregnancy, split up with the father a couple of months ago, he says hes going to be there for the baby, but not acting that way, we are barely speaking, unless i text him with updates regarding the pregnancy i dont hear from him. We know we are having a son, and ive decided i want a 4D scan when i hit 6 months, i want to go back to the same place that i had my gender scan, its 60 miles away, but thats not a problem, we both drive so its only an hour away. I would really like him to be there to see his son in 4D, the way i saw him at my gender scan, partly cos i hope itll start to make him bond. Im trying really hard to be friendly and civil with him, even though i want to get hold of him and choke the life out of him for being such a selfish dick, he hasnt paid for a single thing for this baby, where as im working to pay for everything, got a house full of baby stuff and im starting to feel resentful that hes not contributed a thing, but thats another story, hes a decent hard working bloke, and already has 3 kids who live 200 miles away with ex wife, so this pregnancy thing might not be knew to him, but it is for me and i just want him to take more of an interest. So back to my original question, is it unreasonable of me to ask him to come to the scan with me?

You can ask. Afterall he can say no

Ask, he'll probably want to come. I think blokes aren't as excited about pregnancies as they are about babies. I suppose it might be hard for them to bond with something they can't see or feel.

What is the 4th dimension? Sounds like something out of sci fi.
It's not unreasonable to ask him to come, but as the relationship is over and you are barely speaking I would not be surprised if he refused to come. To me this is something "couples" do together and you are no longer a couple.

Sounds to me like the scan is just the tip of the iceberg. You need to have a discussion, sooner rather than later, as to what he really means by "being there for the baby". Unless you decide what this means together, you'll end up bitter and resentful about his lack of involvement, which will spoil his bond with your son.
