16 weeks today and need advice please!!

Hello!

So I'm 16 weeks today and I have a dilemma. Me and my boyfriend live together and are on the same page about almost everything. Well he wants to continue to see his family (his mom who thinks that covid19 is over, his sister who is still having friends over every Saturday.. and well his dad, hes staying as safe as he can be). Today he is going to have breakfast with them and I have this knot in my stomach. I've already expressed how I felt. Would you just go to the breakfast bc if he gets it you will most likely get it too? Or would you try your best to stay away from your boyfriend which is hard because we live together ...... help!!
