Mine never had anyone the first time, and I'm pretty sure doesn't have anyone this time.
He has been online looking at porn before, so there is that--but right now there is nothing with a real human.
I too went nuts looking for it--but the "signs" just aren't there--the mad testing/phone calls, emails--nothing. He can barely type, he is depressed, has gained weight, is supsicious of strangers--unless someone REALLY came on strong, he wouldn't respond. And he is suspicious of people that DO come on strong....
I sometimes don't know how *I* got him!lol.
From all the lurking I do over in Infedelity, if that is the case with mine OR yours, we would both do better to completely drop the rope, and that would be my plan. They say that about 10% of the truth darts will "stick" if there is no affair, and if there IS one, the percentage is miniscule. I NEED my darts to stick!!
If you get on "friendly-ish" temrs with your H, you can just basically ask the question--are you seeing anyone? and see what he says. Some guys I am sure realize this is NOT a good time to start another R. Yours may be one of them. And if you don't act hurt and all that, he may just be honest with you.
Just be very nonchalant--hey, H, it doesn't matter to me at this point, I'm just wondering...
If he says yes, just quietly say "OK" or whatever and come back here and scream!lol. He didn't "win", you didn't "lose". You know the truth, which is FAR BETTER than what you are doing to yourself.
I think it was right to stay away from your dad--he definitely has "issues". Try not to let anything he says "stick" with YOU --they are NOT truth darts he's throwing at you!!
