Is AUTHOR wrong in the post ? POST : Before you ask this isnt like my gf of 5 years. This is a FWB ive known for 3 weeks. We met on Bumble.

She is completely opposite of me politically, but she is also sexy af and its probably some of the best sex ive ever had. (Ive only had two girls before but thats beside the point)

Shes an "activist" type who is very much into the political scene so I pretend to agree with her as she straight up despises people on my side and would probably have ghosted me after i admitted it.

Im pretty good at understanding the other sides logic so I have convinced her we're like political allies in addition to being fuck buddies.

My sister who knows me has noticed that ive deleted a bunch of mild political stuff off twitter and I admitted that Im pretending to get with a girl. She says i should just be honest even though we might break up. My pov is that FWB arent that serious and as long as she enjoys the sex whats the issue?

AITA.
