I need a book to read about this scenario. I’ll keep it brief.

To start I’ve been on the edge with loliness for a long time. I’m a single mom (27F) to 3 kids (tweens)

•I’ve known this couple (35M; 39F) for over a decade (through mom group); on the outside they have a typical marriage 3 kids (tweens)

•husband is hot and wife realizes sexuality (3 years ago); relationship opened.

• wife marries woman (not legally) and that couple is given a house (one of husbands properties). She moved in. “Main house” (farm) is kept for kids. Husband finds girlfriend.

•the two rotate in and out of house keeping the kids centrally. Wife wants to stay “semi private” and doesn’t want people knowing extent of the situation.

•husbands GF says/does something that “goes too far”; gets dumped// this is 8 months ago

• 3 weeks ago I bump into husband in chance encounter. Exchange pleasantries and move on abojt my day.

•husband texts me (unexpected) and soon I realize he’s texting me everyday. I ask wtf is up?

• he admits to me he’s pursuing me and situation with wife as “consensual adultery” I say ok cool.. is she cool with me? He says yeah and she texts me approval. So we get busy.

•sex is great, we match in a lot of ways but I’m seeing s power imbalance. (Already aware of mine, it’s wife that seems to call the shots)

•husband does most heavy lifting of child rearing nearly every night (he gets two nights to himself), house chores, working a demanding job 60 hrs a wee (wife does not work), maintaining farm, and and he’s starting to sound like a single parent (like me) even though he’s not.

•I’m highly opinionated and have held my tongue this far. He knows by some of the things he says about their dynamic that I found extremely unequal and unfair)

• meeting with them tomorrow for “family fun night” which we’ve done before as I’ve already known them and my kids have played with my own. Not really going to go into relationship details (although my kids have already seen him take me on a date?)

• experiencing NRE pretty heavy and I’m enjoying it (yes I’ve done some research) I don’t want to fuck this all up but I also don’t want to see people I care about used.

•wife told a mutual friend of mine that I’m dating her husband and she’s happy about it. Without my permission. (I don’t really care but.. still, what happened to that privacy?)

•I only know this bc “friend” approached me about it. Wife told me of the encounter but not that she spilled every detail. Thank god my friend isn’t really an enemy. 

• what’s a good book to read about this situation please and thanks.
