I went for my covid booster on 11th December and when I got home my partner started complaining he was feeling a little rough. We started sleeping in different beds from that day. He got full blown covid symptoms 3 days later and went for a PCR. We've just woken up to a positive result text 
We were both going to head to our respective families this Christmas so weren't planning on spending it together. In a bid to not ruin Christmas for everyone my friend offered to let me stay in their empty house as she's not there for the next couple of weeks. I've taken 2LFTs which are negative and I'm about to drive there shortly. So this is me exiting my covid positive household 6 days after my partner started getting symptoms.
I'm planning on taking LFTs everyday and a PCR in day 9 of my partner's symptoms (so 3 days since leaving the house) and if all is negative and I am not showing covid symptoms then go ahead with the original plan to my family's home on 22nd (the day my partner can exit isolation).
Do you think this is enough? My family are fully vaccinated but some are clinically vulnerable. I'm trying to be extra careful not to infect them. I feel fine at the moment other than a bit of a scratchy throat. I will be isolating in my friends house even if I don't need to as fully vaxed and will wait a couple more days to allow any more proper symptoms to develop before going for my close contact pcr. Just worried really. How long after close contact did you start getting symptoms?
If I get symptoms or test positive in his 10 day isolation then I'll head back to my partner's house and spend Christmas alone
