I think that if the OW does check his phone, she will see that HE called YOU!!! And if you keep him wondering what your up to, he will probably do it again! Isnt that much better than seeing you called on his call history? hehe.
I think that if you just let yourself have a day off from all of this drama you will have accomplished a lot for yourself!
Good job today!
I guess I gave the wrong finger to the wrong man...
