I was cheated on as well so my gaurd is up! Like FORT KNOX! I am suspicious of everything because I am so afraid it will happen again. I have messed up alot of relationships because of it. But that's not so bad... I feel like that they knew going into it I had trust issues. And no they don't necessarily have to spend the whole time with me proving themselves, but at least working on gaining my trust. Being upfront about everything so I had nothing to doubt. And they obviously didn't care to or just weren't all that trustworthy and are gone.
I would rather be alone then feel like the person I am with is someone I need to watch.
You obviously built trust with your wife despite being cheated on before and I'm sure she knows it happened so in my opinion she violated your trust. Even if she didn't physically do anything, or even if it's as "innocent" as she claims it is still a betrayal.
She would not have forgotten to tell you that she caught up with an old friend after 10 years! That's BS. I might forget to lock the door, turn off the iron, go by the post office, you know stuff like that, but I certainly would not forget that.
If you questioning her pushes her away that easy then it would appear as if she is guilty of something. If it is nothing she wouldn't get offended. She would understand that you feel the way you do about it because of the way she handled the whole situation.
Gosh I sound so jaded but it is so hard to trust people to begin with and then you do trust someone enough to love and marry them and they throw all that away because they just can't tell you something as simple as finding an old friend or whatever the case may be. it just makes me mad.
