This is a complicated one.
STBXH and I split four months ago, amicably (although he did not want to split). We are both now dating new people; I'm mine is a more casual relationship because of distance and the fact me and him both have a young child we want to prioritise so we often go long periods of time without seeing each other. Lockdown won't be an issue for us - I saw him at the weekend, and I'll see him again once lockdown is lifted.
STBXH seems to have jumped headfirst into a serious relationship. She sounds lovely, I'm happy for him. However, he has told me today that he will continue to be seeing her throughout lockdown. He lives with his mum, she lives in a flat share which includes a teacher and a nurse. Neither are therefore eligible to form a 'support bubble' with each other if my understanding is correct. She also works outside the home.
Our DS goes to school, and STBXH also has another child he has contact with. Therefore my DS is already being exposed to three different households (mine, his dad's, and his sister's) on close proximity as well as through his school, his sister's school, and his dad going out to work. I'm a single mum and could add my mum to a support bubble but I won't be because I want to minimise the number of extra households he is unnecessarily exposed to. In fact I could actually form a support bubble with the guy I'm seeing because we are both single adult households, but again, I won't.
AIBU to say to DH that if he is insistent on still seeing his new girlfriend, I don't want him having DS too? I don't want to restrict his contact at all but he doesnt even seem to have considered that he is unnecessarily exposing our son so a hell of a lot more risk!
Ready and willing to be told IABU, just struggling to think straight!
