He might just be looking for a friend, or flattered that she might find him attractive.

It's obvious that your insecurity with her makes him feel uncomfortable, like he can't socialize with her. After your friends left, and you asked him "what were you thinking?" it might have come across too strong, and upset him, because you basically accused him of cheating on you in his eyes. Still, if he knew how important this was to you, he should be willing to work with you and explain to you that nothing happened and that he loves you.

He needs to understand just how important this is to you, and you need to let him know. Just sit down with him and tell him what you told us. Hopefully he'll understand and be willing to work with you on it.

Cigarettes can sometimes take 15 minutes, because when you smoke cigarettes you start talking, and you might decide to have another to keep the conversation going before going inside.

If he really is a great father and husband like you say he is, then he's not going to compromise his relationship. If he cheats on you with her, he's cheating on you and his best friend.

Just because this chick is a sloar doesn't mean you should second-guess your husband. I was cheated on by my ex for a year and a half while we dated. The entire time she was banging this other guy, and I found out one night and it changed me forever. I know how it feels to be cheated on. When I got with my current girlfriend, it took me a while to trust her, and she's very social, especially at parties. I would always think she's cheating on me, or might be flirting with someone while we are at separate places in the party. After four years, I know she hasn't cheated on me, and I feel safe with her talking to other people, even if I know they think she's attractive.

Jealousy is terrible, and can eat you alive. Try not to let it get to you. And talk with your husband about this. I hope everything works out.
