<human>: Me [20] and my girlfriend [18] have been together for 2 months, and it's been the most passionate and intimate relationship that I've ever been in. Just the thought of her provoked butterflies. Anyway, she kept telling me that she's keeping a big secret that she's too afraid to tell me because she fears that I'll stop loving her and will leave her. Didn't want to force it out of her, so I told her that I'll wait til when she's ready to tell me.

Anyway, the past few days have been quite rocky and I've been somewhat suspicious. Ever since I told her that I loved her, she has been more distant and avoidant of showing any signs of affection other than sexual arousement. I've tried talking to her about it this and last week a few times, and she kept avoiding the topic until I forced it, at which point she got really angry. Anyway, she told me that I have nothing to worry about as all of my assumptions are false.

My bestfriend thought that this was suspicious as well when I told him about it, so he did some basic bypass hacking on her Facebook account, and it turns out that she is in another relationship with another guy for the past 2 years. Found out about this three hours ago, and I'm still in shock.

Give me a shortened version of the text
<bot>: Was suspicious and found out that my current girlfriend has been and still is in a relationship with another guy since 2 years back. Feel greatly betrayed and deceived, and not sure how to handle this.
