Has anyone ever just known in their hearts that DH/DP was cheating?

Even if you couldn't find concrete evidence?

Just have a really strong suspicion! DH is never interested in sex and always has his phone on silent. Apart from that I can't think of anything else.

He does go round to see his daughters from his first marriage twice a week (suposedly) but apart from that the oppotunity isn't there.

Think I'm going mad!!!!

Trust your judgement. It's rarely wrong. Good luck.

Trust your instincts above all, but also go and verify them. Check the phone, telephone the daughters and forget the notion that apart from his visits to them, there is no opportunity. Yes there is, when he says he is at work.

Have you spoken to him about his disinterest in sex? What's his general behaviour like at home?
