Want to contact the OW... Need an Interfriendsion!!!

Hello sisters. so, I am on day 7 of NC with the xN and having a really strong urge to contact the woman he was with prior to us meeting to help me not feel so alone. From what I know, she is now married (to a guy she met right after breaking up with the N) and from everything I have heard about her from the N, she just (like me) started wanting more from the N and things then unraveled. I always thought it was a bit of a red flag that when he first shared about her to me, saying that he "saved" her from being unemployed, having alcoholism and an eating disorder. I also noticed how he could not even talk about her without seeming to go into a place of deep anger. I cant remember him ever saying a nice word about her other than that all of her "successes" were "because" of what he did for her. And then of course I know the part where he says that his "trust" was forever lost in people because the whole time they were together (5 years) she told him she wanted the same thing he wanted (which was to never get married and never have kids) and then they break up and she is married within that same year. He told me that after living with her, he would NEVER live with another woman again because of how much she nagged him and tried to control him. I held on to his words and hoped for three years that he would sing a different song , that he would SEE, that he could trust ME, and I held on to hope (or more like denial, delusion) that our relationship would progress to the type of committed relationship I wanted. Of course, it didn't. the moment i even brought up the idea of moving in, he withdrew. when i mentioned that I am turning 32 this year and that i feel that my opinions on having children are changing, he withdrew. Perhaps I want to contact the xN's "ex" to find out how she moved on? Maybe I want someone else who knows him to confirm that he treated them just as badly and that they too wanted something more for their life? Or perhaps this is just my habitual obsession over him, or anything pertaining to his life and to reach out to her would only set me back another week.
