She Said Her Sister Deserved To Get Broken Up With After She Cheated On Her Long-Term Boyfriend, Who Treated Her So Well, Just Because She Was Bored

This woman has a 27-year-old sister named Anna, who was in a relationship with her 29-year-old boyfriend, Mark, for around three years. The pair shared a pet dog, lived together, and seemed like a perfect couple.
“Mark was a good guy – stable job, treated Anna really well, and was basically part of the family. I liked him, and even our parents adored him,” she said.
But, out of the blue a couple of months ago, her sister approached her and claimed to feel bored with Mark. Anna apparently thought that he was “too predictable” and expressed how she missed the excitement that came with dating.
She tried to tell her sister that was normal after being in a relationship for a while.
“And I suggested they plan something spontaneous or talk things through, but Anna seemed set on causing drama,” she recalled.
So, she soon found out that Anna had been secretly flirting with a 25-year-old guy named Ethan from her gym. When her sister came clean about that, Anna swore she was only having some “innocent fun” in order to spice things up.
She, on the other hand, believed her sister was taking a major risk – and she told Anna that, too. Regardless, her sister kept flirting with Ethan anyway, and eventually, it escalated into full-blown hookups.
Then, when Anna accidentally left her phone unlocked one day, her boyfriend Mark finally discovered the affair. Her sister’s texts with Ethan had been open on the device, and Mark saw everything.
As you can probably imagine, Mark was heartbroken, and he wound up quickly breaking up with Anna. Her sister was devastated as well, but she didn’t seem remorseful about hurting him.

Instead, Anna was supposedly more upset since she didn’t think Mark would find out about the cheating. Her sister only “wanted some fun” and didn’t intend to ruin her relationship with Mark.
Once the breakup was official, her sister also called her crying over it – saying Mark was “dramatic” for ending things after just one mistake.
“And that Anna didn’t deserve to lose everything over a fling,” she added.
“She wanted me to comfort her, but instead, I lost it.”
More specifically, she blew up on her sister and stated that Anna deserved to get broken up with because she cheated and hurt Mark – who treated her wonderfully.
“I said Anna made her bed, and now she had to lie in it,” she revealed.
This pushed her sister to hang up the phone on her, and Anna proceeded to tell the rest of their family that she “kicked her while she was down.” She’s also getting accused of being a horrible sister for not supporting Anna during such a tough time.
Thankfully, her parents agreed with everything she said – despite realizing that she was a bit harsh. Still, other relatives think she should have been nicer, given the fact that Anna was already dealing with the fallout from her cheating.
Everyone’s mixed reactions have now left her wondering whether saying that her sister deserved the breakup was really so unreasonable or not.
Is it natural to feel less excitement as relationships become long-term? Was feeling bored any excuse for her sister to cheat? Would you have said the same thing to your sibling in this situation?
