I am sorry you are having a rough time of it. maybe somewhere in you you think he is missing out on something since he seems to want a 3some. those type things are for very few in the world I think. they do cause alot of trust issues but you seem to have had this issue before the last time you did it. here is how I see it as an outsider....you were ok with a 3some when it was your friend....but not ok now that it is his friend. I do understand how you feel though but they work together so I dont think telling him not to text her and talk to her is going to work. just try to move forward and be assured that he is with you at night. right? good luck hon.
