@ScoobySnacks2017 it is very tough and sounds like you have had a hard time health wise. make sure you look after yourself physically, and mentally (sleep healthy food etc) to help cope with the emotions.
It's natural they will want foster carers but it won't be forever.
I'll tell you what we did, which was encouraged by social workers, and how it has worked out for us.
Almost exactly a month after our three year old son moved in, we met foster carers in a park for fun and ice cream. Ds knew it was going to happen (don't mention until it is confirmed and even then I said Hopefully it will happen because they are very busy and had other kids to care for).
I'd always plan it well and never just bump into then.
I told ds he would go And Come Back in our car. He would come back home with us. The visit was not, and never has been, to their home.
I warned ds foster carer would have new children to care for as this is her job, to look after children before they find their new mums and dads. She brought the new kids with her.
Ds was fine. Happy to see her, not upset etc. I was on tenderhooks! But all was fine and we would have dealt with a tantrum if necessary!
After that we next met at about 2-3 months into placement (his birthday) then about 4-6 months in and now we meet approximately twice a year. This is completely our choice, we like the fact his gorgeous lovely foster carer is still a part of his life. But it is 100% optional.
He treats her like a distant relative he is happy to see. But not that bothered to see.
We've been able to do this because she lives quite close (about 30 mins by car), she is genuinely lovely,
I feel very happy to see her and she is happy to see us.
We have a birth dd and she has birth kids too and we talk about all the kids.
I'm not recommending this for everyone but it works for us.
I always tell ds it was the social workers' choice to make us his parents, and we love him very much. Foster carers look after children when they need it but we are mum and dad.
He missed foster cares and has said before that he wanted them to be his parents. It does hurt butt it does change over time. It's not his choice to make and with time he has settled in well (over three and a half years now).
Good luck.
