Like I said in a post upthread, I just don't get why the OP or her respondents are being criticised here, or why the facts as presented, are being minimised as no big deal. It feels as though there is a different agenda behind these critical posts and that's not fair to an OP who is in some distress and confusion.
As far as I can tell from your other threads Daisy, this relationship has progressed very quickly to the point of marriage and children, you had massive concerns about the friends that he kept (their drug use and attitudes to women), his former drug use and quite recently, evidence that he had been on sex contact sites and interacting with women.
He denied that he had been doing so and despite it being impossible that it wasn't him contacting those women, you bargained it away but the trust was broken. You were honest with him about your trust issues and told him that you would be checking for congruent behaviour with the image that he wanted you to believe.
You've now found more secret, strange behaviour involving sex and this afternoon, he has alleged that he has set you a trap and later said that you wouldn't be hearing much more from him about it.
The denials, the trap-setting and the way he is controlling what gets discussed are the really serious issues here, but for the life of me I cannot see how wanting to contact women for no-strings sex can be minimised by some posters either. And he was doing that, because there was absolutely no other plausible explanation for what you found that day Daisy.
I cannot see how he will be able to convince you that he is going to be husband and father material, or that this behaviour simply points to sexual fantasies that he is too embarrassed to share, but I'm sure he'll give it a damned good try.
However, you sound far too wise and canny to fall for it Daisy and I suspect he is vastly under-estimating your intelligence and your strength.
