Hello Flower and Anon, can I offer you both a warm welcome and I'm sorry for the situation you are both in.
This lockup period has put so much pressure on each one of us, it's different for you being together the whole weekend, because this has been months, 24/7, so to expect disagreement or an argument with the person you love is bound to happen, don't we get cross with ourselves anyway, I do.
It all depends on how much 'give and take' is offered and accepted that keeps a relationship together, which maybe different to a long term marriage or perhaps not, only because you know the 'ins and outs' of each other.
I'm divorced so maybe I'm wrong, but to make up is always fun, again this depends on the situation.
Good luck to both of you.
