<human>: This is a follow up to: 

Hi again everyone.. So I talked to the guy and straight up told him that it wasn't fair for him to do this to his girlfriend and that I wasn't interested in being strung along or involved in him cheating. At first I thought it went really well, he seemed to understand where I was coming from and confessed in the past he had been a player (LOL dodged a bullet).

However.. last night he continuously texts me things like, "why can't we last forever?" and "I don't want to lose you, I never want to lose you". I was never romantically involved with this guy and now he is professing his love to me. Keep in mind his girlfriend lives with him.

Right now I am wondering if I should send these texts to his girlfriend or let her know that this is the type of guy she is dedicating herself to. It all just seems really unfair to her but at the same time I work with this guy.. I'm afraid blowing the whistle will trace right back to me and cause a storm of drama at work.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Guy who was coming onto me while in relationship is now in love with me after I turn him down. Contemplating blowing the whistle on him to his girlfriend but don't want to ruin my work environment.
