Im sorry this is going to be long! I'm just looking for some reassurance or advice at how to smoothly do this. I've read these pages for ever and it does seem blending a household is difficult, I know this from having a step dad too.
My children are 12 and 9, they live 50/50 between myself and my ex and his partner. I'd say 99% of the time it's all very amicable. They've recently bought a house together but moved in together during lock down and it seemed to go very smoothly. We've been separated 7 years and I've been with my partner for 6 years. He's the same age as me he had his kids young and now they are both in their 20s which suits me as I never really wanted to be with a man with young kids (I take my hat of to my ex's partner who is great with my kids).
Now I bought us a house a few years ago, and I'm fiercely financially independent and also protective over my children's space (having had to live with a very strict step father who didn't like me and my sister very much). My partner would not have to be a parent, they have two parents. He's a very chilled out man my partner and my kids mostly like and get on with him, he's very good with them. My bad is that I kept them seperate for a long time and still do to an extent, I just find it easier. Both my children are quite clingy towards me and my son doesn't seem to like me being with 'another man' sometimes. My DS 12 has global development delay and acts alot younger than he is which I think my partner struggles to understand. We live quite an unstructured life where my kids probably rule the roost a little, I'm a bit soft. My ex is much stricter and more intense (I remember) so I think they relax when they come to me and cause it's just us, that's fine. If my partner moved in things would have to change a bit for another adult being in the house. I'm terrified of there being any conflict!!
My motivations are for us moving in together now is that we hardly see each other, due to shift patterns, distance etc once or twice per week and the odd holiday just doesn't cut it anymore. My mental health isn't great in the winter living on my own and also financially things are getting tougher. I just about manage on my own but we'd have a much better life together and the kids would see me more as if not have to work overtime.
My kids didn't bat an eyelid when my ex moved his partner in (although she has told me there's been a few 'your not my mum' moments) so why do I worry about it so much?
I'm so sorry that was so long!!
