Hi
Daisydeedee and welcome to Urban. Sorry it's a situation like this which has brought you here.
As others have said, that sounds like a terrible ordeal for you and your boyfriend to be put through, and you have my sympathy.
It's worth remembering/emphasising that even those of us subject to mental illness and dependant on benefits as a result (and that was me too when I started this thread) have a right to a private life, including spending the night with a partner of our choice now and again without being interrogated about it, so please don't feel like you've done anything wrong (I know it can be difficult when you're being attacked like this)
Going through this is hard for everyone, but even worse if you're subject to mental health issues, so I'd try to get whatever practical help you can. Are either you or your boyfriend in contact with mental health support services? Where I live there is a Citizens Advice worker who runs special sessions for people with mental health issues who need help with the DWP etc. MIND and whatever other organisations there are where you live may also be able to give practical advice and support.
It's also worth mentioning that when it comes to these Compliance Interviews, you can have someone with you, either a friend or a support worker, and if nothing else it's good to feel that you're not alone, that you've got someone on your side.
One of the things which the replies on this thread have shown is that these interviews are often triggered by someone (bitter ex-partner, nosey neighbour etc) reporting something to the DWP which they then investigate, but eventually find to be untrue or not actually a problem. I suppose they have to follow these reports up, but it can put people through a lot of worry while it's going on, particularly because of the insensitive way they go about it, and if you have mental health issues, that just makes it even worse.
But most people who've posted on this thread seem to have got through it in the end, so although it can be an ordeal it's one which you and your boyfriend can and will get through too.
Good luck getting the support and advice you need, and although we can't provide much or in full detail, you're welcome to all the support we can provide - that's one of the things this little online community is really good at.
