First can someone elighten little old me to yadnbu etc...?!
I don't blame you. My ex-'d'h called his female friends (and they were legion) 'babe' etc in texts, calls, face to face.
Long story short and all...
After a midwife appt when I was 7 months pregnant, I decided enough was enough and searched his emails...nothing. Still not happy I went on his Facebook account (I don't have one so was a bit out of my depth!) and oh my bloody good god.
6 months later I left him.
Now I'm not saying that your dh is being naughty at all, but I understand your concern. And I feel he should understand yours and talk candidly to you about it. But we all know that the chances are you're not to get him to.
But he needs to understand how vulnerable you feel, and let's face it, probably a bit lonely when he's at work, no matter how many baby groups you get out to. I think you really need to try to get a civilised conversation going, when you're both relaxed (difficult with a tiny one I know!) and have a bot of time one evening, perhaps the weekend when he's not been at work, and tell him how you feel first, and how his relationship with his female friends makes you feel and just ask him to be honest with you.
Then I guess you have to figure through his responses and see where it leaves you.
I don't know if this is helpful - sure it probably isn't. But I had such a bad experience with a similar thing that I'm bound to be negative. The main thing to remember is that if it makes you feel like this, it IS real, and needs dealing with and it IS NOT YOUR FAULT, tho remember too that your hormones will still be manic!!!
Take care and I hope it all works out!
