Since paternity tests are back on the discussion board, I want to throw a different perspective in this discussion.

A man who only relies on the paternity test as proof of infidelity is an idiot.

A lot of those against paternity tests claim "trust issues" and "accusations of infidelity". While paternity test CAN prove infidelity, I do not find it the best thing to do if you do not trust your partner.

A man who suspects the wife of cheating would need to do more than just asking for a paternity test. He would keep tabs on what the wife or gf is doing, when, how long, with whom, and other things. If he only asks for the paternity test, he only cares about whether the child is his or not, and does not care whether the wife is currently cheating or if she cheated while pregnant or cheated prior to pregnancy.

Think about it, a positive paternity test (the man asking for one is actually the father) only proves that the child is his, but does not prove that the woman cheated in the past or currently. If the man has trust issues, he would need to do more than just ask for a paternity test.

TLDR: A man who only asks for a paternity test cares about the paternity of the child. A man with trust issues would go further than ask for a paternity test because the test is not top priority when wanting to find out if your spouse/girlfriend is cheating or cheated.
