Flame, no overthinking! This is do as I say, not as I (the queen of overthinking) do of course.
I think its much easier sometimes with the ones who obviously like you, but you don't like that much. Because they you don't care enough to overthink. However even that tends to get tricksy, as after a while you start to like them more, and then the overthinking inevitably begins.....
I have a child free night tonight, which I have utterly wasted lazing on sofa watching stuff on catch up. I think I need someone to find me a date tbh, it has been so long I'm not sure I can even make polite conversation with a man any more 
On the plus side this week I have chucked out 2 bags of clothes which are now too big :)
