You are probably sick of MIL threads at this stage. I am a regular under a different name as my DH knows my old name.
I could do with some advice / perspective on my MIL. The view from outside is that we get on well, I am the dutiful DIL, she is doting granny. On the inside there is quite a bit of resentment, on both sides I now realise. Before I get accused of MIL bashing I want to say that I could not ever ask for a better grandmother, she is kind, willing to help, generous to the kids. I have child from previous relationship who she treats as her own. As a MIL it is a different story. It has only dawned on my recently that she can't let my husband go. We are together 9 years. In the start it didn't seem as bad, but the signs were there.
If we were doing anything 'legal' (do do with house etc) she would take it upon herself to ring solicitor.
On our wedding day, she pretended to be sick, music had to be delayed, ambulance called (she got better fairly fast when she realised this and it was cancelled). She changed into track suit bottoms and t-shirt and danced the night away. Everyone knew she was faking (except my DH. On the wedding dvd you can see her giving me evil eyes everytime I am near my DH 
I have had comments about my weight, family and appearance (but not severe enough for me to pull her up on it without looking like the one with a problem).
Lately though it seems to have gotten to the stage where I can't deal with it. We moved house which happens to be beside some of my husbands family. There is a right of way to which we would have been entitled (but it hasn't been used in about 50 years). DH has had a falling out with these relations over purchase of this house. So I advised him to let it go so as to keep the peace and maybe build bridges between them, as we would have no use for it anyway. She rang me and said that she advised DH to ring the council and report his relation. I asked her to let it go, we had enough trouble already, and she hung up on me.
During the above dispute between DH and family, she totally backed him, even when he was in the wrong. When I was trying to be peacemaker, she was the one whispering into his ear about how unfair relations were being to him etc.
She called in last week, and said something about how he had his tea in her house and added "He's my son, he might be your husband, but he was my son first" {insert big fake laugh here}. This line actually was the one that summed it all up for me really.
We are trying to do some renvoations on the house, and she keeps ringing him for stupid little things. Yesterday she rang and said she had a bad pain all day and needed to be brought to the doctor. DH went over and when he got there she announced that she was fine and didn't need to go. Shes gone to visit family today (2 hour drive) so pain must be gone
. She has had falls e.g. she fell and claimed to have broken ribs, went to the doctor who wanted to send her for an X-Ray which she refused. She needed DH over every day to light her fire but was able to continue with her bingo every night though.
Any holiday we went on we got calls to come back - FIL very sick {he wasn't}, her dog is on heat needs to be brought to male dog (I kid you not). We came back first couple of times then I dug my heels in and said no way
She has two other DC's to whom she has departed over a quarter of a million . DH never got a penny (excuse was her husband was the one who was "the boss" and she didn't have a say - he never got on with his father. I am so thankful we never got anything because anything we have is our own. But wen FIL died she asked my DH for the price of the funeral. We were due some money (approx £1000) but the cheque came in her name (Dhs business is based on her premises) and she kept it. I raised it with DH and instead of saying it to her he kept his mouth shut to keep the peace.
Before I get beaten up can I just add that she is not a lonely little old lady. She has a new car, she is out 5-6 nights a week at different things. There is never a "big" thing that she does, but it just seems like a drip, drip that is wearing me down. I dislike myself at this stage because I am allowing it to go on. I have never been nasty to anyone, its pathetic enough but I like to be liked. I have never had a problem with anyone in my life, I have friends and family who I get on great with. But at this stage I can't put up with it.
I don't want to hurt my DH, I love him with all my heart. I think it all stems from his childhood - as mentioned before he never got on with his father, father used to control him with his fists - the other two were golden haired children. I think my DH feels "grateful" to his mother that she loved him (but from my point of view I'd like to know why she allowed his father to abuse him like he did). I have no doubt in my mind that my DH needs counselling but it is not something he would consider.
Apologies for the long, long post, but when I got started it all came spilling out. I would be grateful if anyone could please tell me how to deal with her without my mental health suffering.
