One way street for hospitality meal in ites

I know it's sad, but sometimes you really do have to consider whether friends are as generous as you are. (And your particular friend obviously isn't!)

You get to a point where you have to 'weigh the scales'. What is this friend giving you, compared to what you are giving her?

If you're content with still having her as a friend, that's fine. But if it bugs you, back off for a bit, and see if she comes forward.

Instead of inviting her for meals at your house, you could perhaps suggest eating out instead.

I can understand where you are coming from. I think ‘paying your way ‘ or at least offering is the right thing to do. It really bugs me. Some people just don’t think.
And like you say , it’s not about the money. It’s about respecting the other person .
You know how to get round this I’m sure. Arrange to meet for coffee or go to the cinema. Or suggest , “ Can I come to you this time . Bill’s watching rugby/ playing the trumpet / not too well “
If you can’t get out ask her to bring a takeaway in.

Do you do other things together.

Some people HATE hosting. Others enjoy it. Its okay for visits to be uneven in favour of the person who enjoys visits/hosting so long as the friendship balances out in other ways.

Is she good at phoning or good company on outings etc? If so I wouldnt overthing the lack of hosting.
