Name changed for this.
How do you cope and what do you do if you literally can't stand some almost of your partner's friends?
I'm not just being completely nasty. He has a lot of friends who take advantage of him and use them to do things for them, feed their cat. While they re away on holiday, etc. But then the feeding the cat turns into a long list of tasks left in the house, such as watering the plants and garden, and he actually does it.
They all seem quite burdensome.
My view is I say nothing about his friends because that is only likely to drive a wedge between the two of us. Maybe let him realize this on his own, as he does complain about it.
