Daughter in law or not,Its lovely that you can all still get on.
Mr S and I both managed this with our In laws from our first marriages, his MIL used to come over to Wales to spend the weekend with us, she thought the world of him, sadly she passed away before christmas, she was a lovely lady.
We have both been up to Yorkshire to stay with my other in laws and had a great time.
Life is so much happier and a lot easier when people get on with each other. X X
