I think I know the answer, but I thought I'd ask. Please be kind, I feel shit.
I was with my ex for a few years. OK relationship, got on very very well with his parents. Found out a few days before lockdown 1 that he was sleeping with my best mate, and had been throughout our relationship. Was also sleeping with others. Things trudged on for a bit, but that whole thing created an unhealthy and ultimately abusive dynamic. I ended it, and because it was messy, I told his family that I loved them but that I wouldn't be in touch, because it would put them in an awkward position. He has tried a few times to open up lines of communication, and I have been polite but kept contact formal and short. His sister said horrible things about me, and I kind of get it- it's easier to hate me than to accept the truly awful things her brother has done.
I was in the shop on Wednesday when I saw his father for the first time since all this happened. We had a quick hug and a chat. It was lovely to see him. We were both wearing masks, and I'd sanitised my hands on entry into the shop. I'd also had a negative LFT that morning.
I just tested positive.
So, do I text my ex to tell him? I could text his father but am not sure if that would put him in an awkward position. Or should I wait until test and trace get in touch with me and let them do it? (Would they tell him who the contact was, or would he not know it was me?)
