Need a little advise from anyone whos been in my shoes.
I have been with my huaband for 7 year's married for nearly 4 we have two children under 3.
my husband's mother came to see our son when he was born when went in a huff about something and never seen our son again till he was 6 months old after my husband begged me to try hard to get along so for him I did. we then moved to another part of town 10 mins away and she stopped seeig him again she also found out I had a miscarriage and never said a word about it. she never came to our houae in two years I then feel pregnant with my dd so my husband begged me again to make it better between us so I did again. my sons been going through aome issues ...possible autism....and shes never asked about hia test or how hes getting we moved 6 months ago to right round the corner from her I have invited her round made her welcome but shes made no effort in 4 months not a call nothing. for mother's day when I kindly went to drop of her gift of a big bunch of tulips she informed me that the rest if her family gave her photo on canvase of all her grandchildren ...my children weren't in it 
the next morning ahe phoned to say she doesn't like tulips ......its constantly like this dig after dig not making an effort with the kids so I told my husband that's it shes not welcome at my home and I don't want her near my children !! ....husband has begged me to give her a last chance but I just cant ppl have walked in and out off my life and its heart breaking every time I don't want that for my babies.
anyway it seems my husband loves his mother more than me and the kids so hes walked out on us !! so now I would like to know how I can stop his mum seeibg the kids can that be part of our custody agreement ?? what rights does he and his mum have ?? I want full custody with him getting visit at home only can I do that ??
sorry to go on. any help would be appreciated :-)
