How would you handle this?

Nah, Just the way that I see is that people think that they are being too over protective sometimes. There is nothing wrong with freaking out or jealousy. This is a perfect example of why it's okay to stop her, society has taught us to not be over possessive and that's the reason why some relationships don't last as long as they probably should. Obviously there is a line somewhere but this is behind the line if you do stop her lol. None the less, the fact that she thinks that they may end up having sex is pretty much a wrap. I wouldn't let it happen if it were me but if you seriously think she has more to lose than you do then why are you still hanging on? lol. That alone should be enough to tell you that shes willing to cheat on you lol. You guys are too nice :P

I ignored your statement about not listing any details because... well... there was no details so why would it matter to me? lol. I still find it sketchy that she would Text him, delete him from her contacts and then continue to meet him anyway. What was the point of deleting him from the contacts? just to make you happy? and then continue on to meet him anyway? Yeah sure, you didn't list any details, maybe you should. Who knows? My whole point is, if she admitted to maybe having sex, it's still obviously going to be there because she obviously still cares about him enough to see him. Which is why i was questioning if she really had more to lose than you. There's trusting, and then there's being careless. Because who knows, she could end up having sex with him and you wouldn't even know. All it takes is one lie and I'm very positive she'll lie to you if she did. If she doesn't, you're going to break up anyway. It's no longer suspicion anymore, yeah, things are a bit different according to you now but i keep stressing it. The fact that she earlier admitted that she'd probably have sex with him and is still going to go see him. It's pretty much a guarantee as she seems to obviously not be over him. Stopping her is not a self centered act, majority will see it that way because no one wants to look like the self centered person or over possessive type but people need to realize that it is sometimes needed. I wonder how many people think about how their Ex's would have not cheated on them if they were more protective. Lol. Anyway, it's your call, just wanted to give my opinion though personally I wouldn't let her go. Best of luck and I hope the best but this is waaayyyy too sketchy for me. Because as i said, even if she does have sex, she'll probably lie and you probably wouldn't know. * ESPECIALLY if she has more to lose than you *

There doesn't seem to be much evidence that she'll lie to him. If she was like that then wouldn't you think she'd lie about saying she wanted to have sex with that guy in the first place? Or lie about this meeting, thus avoiding this all in the first place? I don't think being overly protective is a real solution to stopping someone from cheating. If a person is going to cheat, there must be something that isn't getting satisfied in the relationship. And if the other person can't talk to you about it to the point that it leads to cheating, then your relationship wasn't going to last long anyways. Not in a healthy way at any rate. In these situations, you just gotta do what's right to you. So I hope everything sorts itself out and you guys can move on :)

Cheating comes in too many forms. Just because it happens doesn't mean that you couldn't satisfy their needs. Or would you consider someone leaving you because they found someone hotter... you not satisfying their needs? <= Example. None the less, it's as I stated, if she has more to lose, she obviously knows it and it's easier to lie when you're in that situation. Sometimes it's easier to play the role of admitting it first and then talking later to say that you wouldn't just so you can actually do it. The logic makes sense. My point is, shes still shaken up and in that given position it is way too risky either way. Being protective and being overly protective are different and especially in this situation lol. In anycase, what shes doing is wrong anyway. Regardless if she cheats on you or not.
