I posted I chat but have been advised to post here.
I found out in Friday that my partner of 4yrs was having an affair, so confronted him and then left to stay at my parents. We have a 23 month old DS who luckily was already at my parents so didn't witness any of it.
The backstory is XP has been going through depression and burn out at work for months, and I thought I was supporting him through it but it turns out he's been shagging someone at work for the last month. He admits that he wouldn't have told me if I hadn't found out, and says that since having DS I've changed - he still loves who I was before DS but not me now.
Now we're in the messy business of trying to keep things as stable as possible for DS while sorting out what's going to happen with the house/custody etc.
XP has a tendency to get very bitter and spiteful and has been angry in the past and I'm worried this is going to affect DS. He agreed initially to go and stay with his parents so we could go back to the house but is now backtracking, saying he can't stay with them because he's got a cold (his mum has a severe lung disease requiring oxygen 24/7) - he has friends and siblings but I have the feeling that he's not told anyone what he's done yet. I feel like he's trying to shift the goalposts already.
I'm seeing a solicitor on Wednesday but has anyone got any advice in the meantime? Thank you and sorry for the essay.
