Is it necessary to share the property fee when sharing a boyfriend with friends?

What do you think of this problem? 1. If there are three people living in the house according to the number of people (according to the number of people), then the property fee, electricity fee and water fee should be shared equally among the three people. 2. According to the use area, the area used by you and your boyfriend is the same as that used by your friend, but there are many water and electricity costs, and the property fee can be omitted, but the water and electricity fees should be taken. Personally, I suggest three people share it equally. After all, you are sharing for a long time. )
