Hi everyone 
I've posted here previously - www.mumsnet.com/Talk/relationships/2257159-Struggling-with-in-law-relationship-help-please - about MIL and DH's family. Am unfortunately back asking for some advice as the situation is worse..
For those who haven't read my previous post, we are no contact with DH's family due to emotional abuse from MIL when I got pregnant with our child (4 years ago).
MIL has also hit me once. We tried again with her and she had not changed at all. We've now lost all of DH's side of the family.
After DH told MIL that the relationship between us and her wasn't working due to her behaviour on the last meeting up with her, and that we cannot have contact with her, she turned up at our address, got into our building (we're in a flat) and refused to leave until she'd spoken to us etc. We also had texts from other members of DH's family saying to speak to her and "make things right", despite nobody asking for our side of the story.
We then had FIL and BIL turn up several times trying to come in, and MIL sent DH a letter that arrived on his birthday saying she's got no idea what's she's done but we're all flawed and we just just accept her as she is. This was genuinely the last straw for us and we contacted 101 to get some advice. My husband made a statement and the officer warned MIL that she could get into a lot of trouble if she continued with her behaviour, and to not send others to speak to us about her.
We've had periods of quiet and times where there's been unwanted visits since by IL's. I also received some horrible messages over social media from one member of the family. In the lead up to Christmas we had cards and gifts left at our front door, and MIL actually came here and left things for our child and cards for us.
Very recently two members of the family came to our home at a time of day when they know DH won't be awake (he works nights) and asked repeatedly to come in, and buzzing our flat. I answered thinking it was the postman and said he's asleep, I can't wake him and don't few comfortable with you coming in. One of these people was the person sending viscous messages to me over social media. I was being asked why cant we come in, we want to see you, etc. Eventually I was able to get rid of them by just repeating what I'd said before; but was instructed to tell DH they'd been there and he should call them.
As it stands we haven't spoken to the police again regarding this, but I'm starting to feel similar to how I felt previously.. Panicky, anxious and my mind is going at 100mph with worry about what's next. My DH has even said he feels unable to go out or even answer if somebody buzzes our flat in case it's them. We're now moving because of this and waiting for the moving date.
I think what I'm asking is what should we do now? I know what they're doing isn't ok due to how it's making us both feel, and how anxious we both are. DH has had counselling for this, has been on medication and had to have time off work also.
I'm reluctant to report these visits and communication again, I think because I would feel guilty for the trouble it causes, despite their behaviour towards us.
Thank you for reading xx
