You really need to go to couple of job interviews and generally look around for things you want to do. It doesn't mean you should instantly switch your job, but you obviously lack perspective. You need to understand how easy of IT to find new job. Moreover nowdays more and more companies offer remote positions. Pay might be smaller, but you can move further from center and find cheaper place to live. You basically trap yourself with thoughts like 'I won't find better paid job' and 'my partner will never follow me'. There are quite a lot of options between 'live in London' and 'live in the middle of nowhere'.
