Dear RPillerz
I'm an older normie redpilled for years. My post should belong in some shitty subredidt like relationships but I trust more repill bros.
Let's just say that a 25 co-worker ( in LTR herself) is extremely "enganging" with me, and she is really fine. I never really did anything actually to seduce her or anything. A lot of guys here want to fuck her, a lot of betas orbiting aorund her also, but she may have daddy issue so that's the most probable reason she is gaming me so hard.
The problem is: I'm nearly 40, in a healthy relationship with my wife. If I have any kid one day she will bear them. Sex life is good for the last 6 years, we almost never fight, I'm pretty much living a relaxed life and that's all I want.
But this naughty brazilian ass made its effect on me. I feel like a 20 years old incel... I'm losing my appetite for food, my sexual drive for my wife is much lower ( alas ), I start to get nervous around this girl for no reason and thus I know I'm developping a fucking oneitis as a grown man.
After thinking about the possible outcomes, there is absolutely no way a relation with this co-worker can lead to anything positive. In the worst case, I can ruin my mariage and my job.

Please help me rationalize and get out this bobby-trap. I almost invited the girl to eat something today ( and I know she'd say yes instantly ). I must interact with her everyday since we work on common projects ...
I just want to ignore her as I did the past year but I'm completely losing control those past few days.
Thanks to let me your best recipe to cure oneitis as an adult.
