Men with close female friends are far from a rare category... Clearly you did not know yourself well enough to know it's something that you would eventually end up resenting before getting serious with someone... You have no one but yourself to blame for that.
Yes you can focus on yourself as someone suggested and act like you don't need him every moment to fulfill your days... but I think that will only temporarily sugar coat the issue. I'm sure your subconscious will still not leave it alone as he most likely won't change significantly.
"I simply do not want someone who doesn't want me as much as I do."
You really couldn't have figured that out before deciding to attempt to bring a baby into the world for the 2nd time..? It's not like he suddenly increased his frequency of conversing with female friends after you both married.. if he did that's obviously concerning. My point is I'm sure you were also aware he was doing it to some degree before marriage.. did you honestly think he would suddenly change after a marriage certificate (a piece of paper)? Women who think like that baffle me.
I don't know what expectations you had but it seems like you have been living in your own fantasy ignoring what has actually ALWAYS been in front of you until it all came crashing down one day.
