&gt; Personally, I find cheating abhorrent, and my SO should know that. If we're having a kid together, he should know that basic fact.

Okay, but... You understand that someone could just tell their SO that they find cheating abhorrent, and then go out and cheat eventually anyway, right? There's such a thing as lying?

If you don't trust your SO to the point of being willing them to ask for a paternity test, then what's the point of being with that person? You already consider them a possible liar and a cheater, just go ahead and end it.
