Hey there SP I am in the Sacramento area and I hear ya on the HEAT! I don't have AC at my house...so time to head to the coast for some cool air. But it is a spare the air day...
I have to say, a good cure for the blues about thinking about X or STBX is to start having fun yourself. Maybe it isn't fun at first, so then "act as if" it is fun...Eventually...and this could take some time...you will find that you think of them less and less. I go weeks now without thinking of Ex! It also helps if you don't need to see them for other reasons.
