Dp and I don't live together, but as he has disabilities, (physical) we are in a bubble. The problem is Dp is continuing to go into his elderly fathers house on a near daily basis. He is a diabetes and over 80. I can understand that he wants to see him as he lives alone. But Dp's father is mixing in at least 6 other houses, going in and out of theirs and them coming in and out of his.
He is not the cleanest and pre covid I often would see him spit on his own kitchen floor. He still is wearing the same mask since last April and it's filthy according to Dp. He never bothers washing his hands.
I've just had a row with Dp over this as he has told me he was up earlier today with his dad and while he was there more visitors arrived. I asked him to only visit from now on outside the front door and not to enter. He has said he doesn't touch anything in the house just has a chat with him, with no mask on. He said he would just stay away from me instead.
I feel like I am beating my head against a wall.
