My guy and I have been together for 3+ years, recently he has found a new friend at work and is seeing her all the time, especially when I’m at work. I am terrified he is going to leave me for her, he said he’s confused, and honestly, my anxiety has gotten to the point I’ve been having thoughts of suicide and self harm, I haven’t attempted, but it’s getting scary. I see a therapist friday, but am I crazy for being worried? Am i THAT jealous girlfriend? Am i overreacting?
