Hmmm. Perhaps HE’S the one who needs a password change. 
Throughout this entire thing, he has not even once made issue of the email snoopage. Not even a word about it. I even keep bringing it up…no mention. Bizarre. I would have expected the first response to be well, why the hell were you reading my email?
Nope. Just repeated profound apologies.
So I take that as a “no, I haven’t changed my own passwords yet because I’m feeling ambivalent and I don’t want him to think I don’t trust him, since he hasn’t griped about the snooping”.
Sail Bunny:
DO NOT believe this, and feel you must settle for a cheating, lying scumbag. All men do not cheat. There are faithful ones out there.
I don’t have a horse in this race except this: If you decide to have sex with him again, he needs to be tested for STIs. Yes, Thailand has some good HIV policies. Nonetheless: HIV, syphillis, Hepatitis B, gonorrhea, herpes, and anything else the doctor wants screened. He shows you lab report. The doctor is asked to test (including herpes titers), not just to say “You feeling okay? Everything good?” I know too many people who have gotten non-curable STIs from people who swore up and down that they’d used a condom, or their doctor said they were okay based on a conversation rather than an examination. If you feel bad now, imagine how you’ll feel hearing that he gave you herpes, to say nothing of HIV.
So, you’re OK with the Patriot Act then? 
I agree that not all men cheat.
Your decision on taking him back is exactly that - your decision.
However, if you do decide to take him back, do not allow him in your bed again - not even with a condom - until you have seen a negative STD report. He may had decided to take chances with his health and life - don’t take chances with yours.
Well, for $700 you could…
seriously, I hope you’ve had a chance to pause and reflect on what you want to do. This is a big step either way.
You’re young, no matter how bad you feel now, you won’t feel this way forever.
Not all men cheat.
But this one does. Honestly, I’m not sure what more you need to know.
