My DH has recently started up a friendship with a girl he met through a work related conference (they don't work together). She's slightly younger than me but very attractive and single. They have a lot in common and have been meeting for lunches and went for a night out recently. He has been totally open about it and I've seen her messages, which are friendly but usually with a work related twist. I do trust him, but I'm feeling a bit insecure in myself at the moment and frankly jealous that he can have fun lunches and nights out with an attractive girl, without a kid in tow like we usually have.
I'm becoming a horrible jealous and suspicious person and I don't like myself.. But I guess I am jealous and worried about how their relationship will develop.
