Read what you just wrote! You state that you need to take more action instead of sitting and thinking of negative things...then you go right into a negative "if ow is pregnant then I know m is over"
Well it might be over...if that is what YOU want...but I happen to have a best friend whose H left, had an A, had a child, and then came back to her (it was over a few years span)...and they have been back together for 14+ years now...so you don't KNOW with a certainty that it is over...even IF there is a pregnant OW...which, from what I have read, you have no proof!
This is where you need to stop...no really STOP (picture the big red hexigone sign)...when you start thinking something that is negative or makes you sad throw up the STOP sign and immediately change your thought...think about the birds singing, your son's first steps, your favorite fruit and how good it tastes when it comes into season, you favorite funny movie...you have control, use it!
The bottom line is this...YOU HAVE TO BE OK NO MATTER WHAT! YOU HAVE TO BE OKAY AS A SINGLE WOMAN IF THAT IS WHAT HAPPENS! THE ONLY THING YOU CAN CONTROL IS HOW YOU CHOOSE TO FEEL...YOU CAN CHOOSE TO BE OKAY OR YOU CAN ROLL UP IN A BALL AND WAIT FOR THE GUYS IN THE WHITE COATS!
