<human>: Can you give me a shortened version of the text?

DH [50 M] and I [47 F] have been married 15 years, together 17, with two kids [7, 11], have sought counselling to deal with my concerns about his sister [59, single & child-free] whose ideas re how much time she should spend with us are different from mine. 

We live a hundred yards apart in a small town. She would like to attend every school or community social event and sit with us. I think that's a bit much. She expects to be invited to every big or small social gathering at our house. I would like to have some time with my parents or sister without her, since they visit only every few months. In addition to formal events and dinners, she has also invited herself to come with us on our daughter's first day of school (and walk her to the classroom), her first horseback riding lesson, her special Brownie ceremonies, her first skating lesson, etc. 

In the past, my DH has said that she's lonely and wants to experience these things, and we should include her. It got to be too much a few months ago, and things went dramatically downhill. DH and I sought counselling to deal with this, and it has been helpful. We now see her less -- DH and kids visit once or twice a week. 

SIL now tells him that  this (seeing less of him and the kids) is the worst thing that has ever happened to her. I feel guilty, because I have really enjoyed going to events and not feeling like the third wheel on her date. I am considering asking if she would do a session of family counselling with us, but I'm afraid that this would reinforce her sense of entitlement. Has anyone involved in-laws in a family counselling session? How did it work out?
<bot>: Single, child-free SIL wants more involvement with us than I'm comfortable with and says this is the worst thing that has ever happened to her. Would family counselling help, or is this just going to reinforce her sense of entitlement?
