Hi everyone,

I'm new here but I'm at my wits end and don't know what else to do.

A bit of background. I have been with my partner for 18 months. There is a bit of an age gap (I'm in my thirties and childless) and he has two kids from his previous marriage, SS18 and SD15. 

SD lives with Mum and SS lives with us. This is where the problems come in.
