Things that DH likes about my DM:
She has got to know him as a person - she has attempted to learn about his job and his interests.
She acknowledges that he makes me happy even if we don't run our relationship the way she would like.
She spoils him and always bakes him a cake.
Her house is pleasant to visit. Even now she is disabled, the bathroom functions, the bedroom is nice and she insists on taking us out to some new place she has discovered for dinner.
Things I don't like about my MIL:
She instantly expected us to be friends and me to call her mum
She knows nothing about my job except to say my DH's job is very responsible and important a lot. It isn't and I am the major breadwinner. There was also the priceless time she implied I killed people over Christmas dinner (work in the NHS, tangential part of a major news story)
She expects me to do wifework and DH to do none. If a birthday is forgotten it's my fault even though it's a member of DH's sodding family.
The house is awful to visit. The bathroom barely functions. Flushing the loo is a matter of chance. Towels are threadbare. Food will likely be frozen pizza. She has £100,000s in the bank compared to my DM who is on benefits.
OP - I am sure you will be fine.
