Coparenting after infidelity is never simple, but having to do it after your spouse cheated on you and had a baby with your best friend?

That’s a diabolical level of disloyalty that most people will thankfully never have to navigate. Except for her. She’s handled it with more grace than I certainly would, but now a birthday party guest list has her ex and his mom coming at her, and she’s not backing down amid the contention.

This 35-year-old woman shares three daughters with her 37-year-old ex-husband, with whom she has a long history, as they have known one another since they were children themselves.

Also, she and her ex share this electric chemistry that has not eroded with time, or the fact that they are no longer married. The day they did tie the knot was the best day of her life, but that quickly crumpled.

“What I wasn’t aware of was that he was having a long…affair with my so-called friend. It still [angers] me off because I trusted her; she’s been to my house, smiling in my face while this was going on,” she explained.

“Also, I’m not blaming one person; I’m blaming both of them. The part that made me want to throw up is that they had a secret baby.”

“5 months later, I found out the whole truth: my ex had another phone. From messages to explicit pictures, lovey-dovey conversations. I was disgusted to say, you give a man loyalty and he still does you wrong.”

She didn’t immediately tip her husband off to knowing about the affair, because she pretended everything was normal in order to gather the evidence she needed for the divorce.

She just couldn’t believe that her husband had three kids with her while cheating behind her back with someone she truly cherished.

It’s now been four years since her divorce was wrapped up, and she’s getting back to dating new guys. Her daughters do spend time with her ex at his house, so they see his affair baby, their half-brother.

Her daughters have grown closer to the little boy, as her former bestie has kept him away from them until the last year. Her ex’s affair child is so attached to her girls that he cries when they come home to her. She’s met the little boy on several occasions.

What’s curious is that her former bestie is no longer involved in the little boy’s life, so her ex is essentially a single dad. Her former bestie pops up from time to time to ask her ex for money, but that’s it.

Her ex is definitely not living his best life in light of the divorce, as he used to be attractive, but that has faded along with weight gain, and you know, her former bestie stealing his soul.

Her daughter will be celebrating her sixth birthday soon, and she questioned her about who she would like to invite to the upcoming party.

Well, her daughter surprised her by saying she doesn’t want her half-brother included.

She made sure her daughter was positive about that, as, despite everything that happened, she does inspire her kids to have a decent bond with their half-brother.

“I got a text from my ex, he was asking if I know what I want to do for our daughter’s birthday. I told him I had everything. I decided to tell him, I told him that our daughter doesn’t want his son there,” she added.

“I already knew he was going to blame me and say I made her say that. I don’t speak [badly] of their brother because he did nothing to me.”

Her ex flipped out on her and said it was all her fault. She did her best to calm him down, but she eventually hung up after getting nowhere.

Her ex then went to his mom, whom she had to put in her place, as she wasn’t about to let the two of them team up against her. Her ex’s mom thinks she’s heartless for allowing her daughter to exclude her half-brother from the birthday party.

She’s not sure her ex’s mom even understands it’s her ex’s fault they’re all pulled into this mess.

Anyway, she’s left wondering if she’s wrong to stand by her daughter’s wishes for the birthday party guest list.

A six-year-old choosing not to invite a specific guest to their birthday party isn’t a federal offense. The idea that she somehow orchestrated that is absurd, even though her ex and his mom can’t see it.

It’s her daughter’s party, so she should be in charge of the people invited, even if she is just a kid. She should tell her ex that if he’s so upset by this, he can throw their daughter his own party and include his affair child.
