I don't reaally think it'd cause problems for their children, they'd just have the best of both worlds I guess haha. They're mum or father would show them all the magical stuff and the muggle one would show them the muggle stuff.
But the muggle one might not really understand all the magical stuff, but yeah...

Yes, but Voldemort wasn't raised by his parents, his father left his mum and his mum died before he ever got the chance to remember her. He really was raised by muggles, until going to Hogwarts.

It wouldn't create a change for their kids. It would just make them half blood. You see loads of them in hogwarts and theyre not unhappy or anything. Seamus finnigan is a classic example Of a half blood and he's ok. But when it comes to the point when the wizard/Witch has to reveal their muggle partner about what they are...that would probably be a problem. It would be a shock, and sometimes it might even cause them to split up, but for some, they just work through it and get over it.

Sorry, have somehow managed to post my response to another thread here.

I think the whole relationship would be harder on the Muggle, especially if they had a child. The child would most likely become magical, therefore, would want to experience that to the greatest measure. So, if the child wants to learn more from the start, then they would obviously be spending more time with the Magic parent. So the hardest part of it all, would be the emotional connection the Muggle parent would lose once that began. That is one thing that you don't really see getting touched on. How the magical children are raised in the mixed families. If they're pure-blood, then that is obviously an easy way to be seen. Muggle borns too, parents don't know any different until that day, such as with Hermione Granger and Lily Evans. You know?

Well I think the muggle of the relationship will be in a bit of a shock for a while. They might end up getting divorced. Or maybe the witch/wizard of the relationship just doesnt end up telling the muggle until a time that they feel is right. (when their child gets a hogwarts letter, or when they are in a situation where them using magic in front of their muggle partner is essential.

I think that would be hard if the Magic person of the couple did any work/job. How would they explain that to their partner? I don't think it would even continue to a steady-relationship stage if one of them just vanished for 8 or so hours every day, and would not say where they went to school or what they do.

Of course, there's a chance that, say for Seamus's mum or Snape's mum, they weren't employed in a wizarding job and therefore didn't face that awkward questioning, which I guess is what happened to Seamus's parents since his dad didn't know until quite late (after they got married, maybe?) At least that's the impression I got.

I don't know, are there many Magic folks who choose to do normal non-magical jobs or not go to a magical school but instead go on to a normal school and college? I'd say that'd be pretty interesting to think about, too. Although, well, they might be able to cheat sometimes, specially if they were actually magically trained at home or something.

About the Leaky Cauldron/Hogwarts/Diagon Alley/Platform 9 3/4 issue, I think it's sort of a Secret Keeper thing where all magic people are secret keepers. Like, the Dr. Grangers were on the platform staring at the Hogwarts Express. So were Mr and Mrs Evans and Petunia in Snape's memory. So I reckon they could also go to DA/Leaky/Hogwarts (DA and Leaky is confirmed, since the Grangers were at Gringotts, but I don't know about Hogwarts. I would think they could, though.)

The muggle parent would have to deal with wizards/witches with bad attitudes. I reckon some issues would cause problems but its difficult to know until you're put in that situation. I guess it would be like one culture accepting and living with another.

I think it would also be quite hard to the wizard or witch in the couple. Andromeda is a classic example of how they can be expelled from the family just for falling in love with, what is classed as, the wrong person. I don't think her husband would fully understand the extent of what had happened because she had married him.
In my opinion, the muggle in the couple could cope fine, because they would just live as normal and pretend that their child had gone to boarding school. I admit, it would be quite a shock, but it's the same shock that all muggleborns get and mainly cope with.

I say the Muggle partner would definitely feel left out... Knowing about this magical world but never fully experiencing it. It would definitely put a strain on the relationship!

I think it would be very difficult to be a muggle in that relationship. Imagine that your husband and children could all do magic and had such fun and you were left in the normal muggle world? It couldn't be much fun...
