It should bother you, that is only normal. They are truly ridiculous. My ex shoves his relationship with OW in my face also. The more I completely ignore OW, the more baffled my ex is. I can say that what Snodderly is saying is true, he wants a reaction. If you remain loving, kind, and sincere, it will bother him even more.
