I need all the advice I can get?

my boyfriend masterbated while text messaging his ex last night while I was asleep. I caught him. he genuinely feels bad. I do feel hurt, but it was still just masterbating and she didnt know what he was up to. The rest of our relationship has been great. This was the first time. what do I do? Stay? Go?I need all the advice I can get?
ok i wouldve been kinda pissed... 1st ill wonder why in the world is he textin his ex?? why so late?? why masterbate?? its all signs that they just may be messin with each other or he still have feelings 4 her... i would ask him 2 change his phone # %26amp;%26amp; if he does it again then i would break up with him without any doubtI need all the advice I can get?
DAMN!!





that's messed up!! lmao!!
GO!!!!


If he has done it once, it has not been the only one ,


Ut sounds to freaky:He might also masturbate to the singn of a dearg corps or a sementery where the corpses might be having an orgt...


Any who, YOU and only you are his girl now; He should respect that !!!
stay, if he'll call her up while u are listening on another and admit the situation to her and apologize for his actions, but keep silent. Don't let him out of your sight when u ask him to do this or he will warn her first b4 calling.
you should do the same,if he catches you,he will never do it again,if he dont,you will feel great
