I can relate to your intense anger after discovering that H has been lying to you, especially after all you have been through. Kind of recolors everything else he's said and done recently, huh?
However, there is a whole lot of missing data here. Also, phone calls do not necessarily equate infidelity.
I know...I would be thinking the same thing, but I really do think that there are many more possibilities surrounding this cell phone issue.
I imagine that your system must feel like a wild horse fighting off a bear right now and I empathize with you from head to toe.
