Input: Okay, so I (26m) have known my coworker (36) for I wanna say a year and a half. I have always had a lingering attraction to her, and we have a very playful/flirty relationship. Its never been said but shes sort of like my work wife and im her work husband.

Her husband ALSO works with us, in a separate area. Like in the same office but we never see each other. He is like an acquaintance to me, and whenever they get together I immediately notice theres a change in her demeanor, she acts much happier with me. He is also out of shape, old, and slightly short. Where as I am younger, and 6'2, and take care of myself. 

Needless to say, there have been several side eyes directed toward me by the husband.

Well, recently shes been coming to work sadder and sadder, or i guess quieter and quieter. She opens up to me that she and her husband are separating, which makes sense because he hasn't been seen around work for awhile. He is now moved out of his house with a relative.

Two days go by, and we're constantly opening up to eachother. Eventually, she invites me over to her house to eat dinner since shes lonely and her kids are at a friends house. 

Long story short, we have sex in their bed. After they've been separated for three days. I told my sister and she thinks im terrible for not giving my coworker space and giving her time to think. She also says i may have broken up a family. 

I respond that as long as shes not with anyone, its fine. But I actually do have my doubts.

AITA for having sex with a married woman after three days of separation?
