MIL is a nightmare

So we currently live with my MIL while we save for our house thankfully this arrangement is coming to an end as we have now got our mortgage and start viewing houses next week but I'm still facing at least another 4 months minimum living with her. Initially we got on well and there are days when we get on but these are always dependent on her mood. We got married in May and since then she has gotten worse. Her friends and she herself tarnished our wedding causing ridiculous drama which since then has continued to the point of me actually contacting one of them on Facebook after he left a very negative review on our photographers Facebook page because the photographer didn't get a picture of him and his wife (who aren't close to me or my husband) .

My MIL always throughout the whole planning etc has been less than enthusiastic always making comments and digs where she could. This is just a snippet of her behaviour.

The day before our wedding her friends arrived in Ireland and their cases remained in the uk due to a faulty baggage belt. Instead of letting them sort it out and geting the help of other friends she brings this to the attention of my husband and suddenly it becomes a huge issue he has to fix resulting in him getting a friend of his to collect the bags that night.

As his friend promised to drop the bags off at 11 the next day (wedding was at 12.30) from 11 am baring in mind my husband is trying to get ready for his wedding, his mother and her friends constantly bother him over where his friend is despite them being offered outfits by other guests so his morning is ruined. These same guests then walk up to us at midnight at our reception asking how they are getting to the airport the next day (I thought this had been sorted as they never came directly to me with this question in the lead up to the wedding despite having multiple means of contacting me) needless to say in the million and one things I had to do I forgot about this. Then they day after our wedding my MIL and SIL make my husband cry as they complain that I made no effort with their guests even though his mum was the one who didn't mingle with anyone but her own guests, didn't thank my parents for the welcome party they threw, didnt get involved in anything on the day but no I didn't make the effort.

Then I find out that my MIL was saying to everyone how her daughter would be engaged within the week, how her wedding would be so different and how it would be harder on her than my husband not having their dad at her wedding (he passed away) , again this was laughable considering this was the 3rd guy in less than a year who had been invited by my inlaws to our wedding, they had been together all of about 5 minutes and less than a month after our wedding had broken up now I have to try and get him edited out of family pictures cause they dragged him into them against my wishes.

Then when we uploaded our wedding pics on Facebook my MIL put comments on the album asking if anyone had gotten any pics of her and her best friend at the wedding as sadly he passed away shortly after it. When people said no she continued to go on and on about how the photographer hadn't gotten a single picture of the 2 of them in all of the 600 plus pics taken knowing full well she never posed for one with her friend. She never asked any of her friends to take one and never bothered asking the photographer or myself or my husband to get one taken. It was even pointed out to her that her friend had not wanted to be in pics yet she still went on and on to the point I had people PMing me asking if I was ok because she was making out it was my fault.

The final nail in the coffin was when we went to sort the pictures for the wedding album with the photographer, after a lovely few hours going through each picture etc it was again ruined by finding out that our photographer had received a really bad 1star review on his business page on Facebook by one of the MIL friends who said that there was no picture taken of him and his wife (who aren't close to me or my husband) and none of my MIL and her best friend who since his death is suddenly being referred to as her partner even though she always insisted they were just good friends 🙄. I was fuming and so embarrassed having to explain who these people were to the photographer. I sent this friend of hers a message saying it was out of order and pointing out to him that A-it wasn't our photographers job to take individual shots of guests and B-I had asked my MIL on numerous occasions what specific pictures she wanted and she never specified and that shots got missed on the day anyway, C- she could have gotten the photographer or any one of her 20 or so friends including himself given he had a fancy camera to take a shot of her and her friend. He hasn't replied or apologised and has said to her he is no longer coming to my husbands 30th birthday party. This from a man of 60 or so. My husband has spoken to his mother and she has not taken any responsibility for her actions or her friends and had the nerve to say she didn't realise that I was asking for the list of people for the photographer but thought it was for our wedding favours (these were keyrings with people's pics in them) but this is all a lie as she knew exactly what I was asking for. My parents can't stand her and I am just done with her and her cronies she is so two faced. I'm near tears knowing she has just caused drama throughout our wedding and after. I really want to have it out with her but as we are living under the same roof I don't want to cause a big argument but I also don't want her to think that what she has done is ok either
