I will try and get a proper job again one day I think (or at least find some way to earn more money as am fine at the moment in a single state but if I do this living with someone thing in 5 years time I want to be able to be more independent iyswim).
I do invigilating exams which is boring but pay is ok. Most people doing it are retired. You get in touch with local secondary schools and/or universities and see how they recruit people. Both the schools I do here they take people in from the streets although some places use council pool staff. University I found out about through XH but you could get in touch directly. Is seasonal but there are a few exam seasons.
The mystery shopping is self employed - there is a thread about it on money saving expert which is great to get you started. Will link later on if you'd like. There are loads of companies and you can decide which jobs you'd like to do - some you apply for and some are self assign. Doesn't make loads of money but gets some and occasional free meals :)
The other stuff I do is exam marking, some in London as I worked for them when I lived further down the country and some at home. I am an accountant and mark exams for one of the boards and for a college. Both pay well - if I did that all year round would have more money but also would have no life 
.
Done my mystery stuff - time to go home and go to parents evening. XH has double booked himself so at least I don't have to grit my teeth and put up with him .
Mr Nice and I text quite a bit - but neither of us minds if it takes a little while to reply. We do text on and off through the day and use iMessage most evenings at some point if we're not with each other. The next two weeks will not be quite like that of course .
I think some amount of compatibility of communication is a good thing
