It hasn't happen to me so I'm not bitter, but yes, I would never again risk having a child or getting an STD from him (since as you all say, you never know what your partner is doing/you can't take their word).
I thought point of marriage was the have a certain level of trust with someone. Once I know we don't have that level of trust then I wouldn't trust him just like he doesn't trust me nor would I want anymore children since our marriage is likely to fail anyway (he'll be the bitter once he realizes he also no longer gets some of the benefits of marriage).
That's just me though...not every woman will be the same.
