Family loyalty can be complicated.

In this story, a woman has a brother who is known to be a “serial cheater.”

His new relationship began as an affair, and she never respected the girl or how they got together.

Now that he is planning to propose, she doesn’t want to be part of any of it.

Are her feelings valid? Read the full story below.

WIBTA if I don’t attend my brother’s wedding?

For context, my brother is a serial cheater and has cheated on the three girlfriends he has had in the past.

It never really sat right with me. It was something that I always felt awkward raising with him.

I feel like he would have an angry outburst at me if I did. I didn’t feel like it was my place to do so.

It is also something we don’t really talk about.

This woman learned that his brother officially got together with the “other” girl.

With the last cheating incident, he basically cheated on his ex with someone he was working with.

The girl he cheated on his ex with knew that he was in a relationship at the time.

Things were already happening between them.

Eventually, my brother and the ex broke it off because the ex found out about the cheating.

My brother officially got together with the other girl.

She didn’t like her.

I really don’t like the girl. She did not make a good impression.

The first time I met her, she visited our family’s condo.

She was sprawled all over the couch as if she owned the place.

I didn’t like it. You would really think, “Who is this stranger in my home?”

My brother never bothered to formally introduce her to me.

She felt like she couldn’t have a relationship with both of them.

I just cannot overlook the fact that she willingly had an affair with someone who was still in a relationship.

I just have no respect. I don’t want to have a relationship with them.

They have officially only been together for less than a year.

I just found out from my mom that my brother was planning to propose to her tomorrow.

She was not keen on attending their wedding.

I have discussed it several times with some friends and some of our cousins.

I told them that I’m not keen on attending their wedding should it happen.

WIBTA if I didn’t go?

She couldn’t even pretend to be civil with them.

I have a civil relationship with my brother.

But I just feel like how he has been acting and his new partner are not people I want to keep a relationship with.

At the same time, there is that element that maybe my family will perceive me as too harsh for not going.

I just cannot stomach having to fake it if I went.
