I believe my girlfriend has left me because of hormonal changes.

Subject: Heartbroken Over Sudden Changes in My Relationship Hi, I'm reaching out because my girlfriend recently broke up with me and asked me to move out after discovering she was pregnant. I’m 27, and she’s 25. We've always shared a close bond and enjoyed a good relationship, despite the typical ups and downs that come with stressful times at work. However, in the last couple of months, my work situation has become challenging. I've been paired with an alcoholic colleague who makes everything more difficult, leaving me to handle most of the work on my own. His behavior has been pushing me to drink again, which I had issues with in the past. I’m stuck in endless conversations with him that are driving me crazy while balancing all the driving and paperwork. Despite all this, I’ve made an effort to be a good partner. However, my girlfriend’s attitude towards me changed dramatically out of nowhere. She stopped being affectionate, distanced herself emotionally, and began making manipulative comments. For example, when I quietly whispered to her at night, she insisted I was shouting. This has been the pattern for about two months. Then a few days ago, she called me at work in tears, revealing she was pregnant. When I got home, she was missing. Later, I found out she had gone to the cinema, which upset me. I waited for her to return, and when I finally checked on her around 11:30 PM, she was asleep on the couch. I took care of her by bringing her water, removing her makeup, and getting her pajamas ready. However, once again, she accused me of shouting while I was merely whispering. Frustrated and overwhelmed, I snapped and ended up punching the fridge. I know it was wrong, but after working tirelessly for 54 days straight and dealing with my girlfriend's harsh words, my emotions came to a head. Now, she has left me, and it's been hard to process her mood swings—one moment she seems fine and engaging, then suddenly switches to being distant and unkind. I can’t help but wonder if she might realize that her behavior was influenced by hormonal changes once the pregnancy ends and hope she will want to reconcile. I feel completely heartbroken, having lost my girlfriend, our dogs, our home, and the baby we might have had together. Our relationship was strong until she found out she was pregnant (she’s about eight weeks along), and since then, things took a downward turn. I'm devastated, struggling to eat, sleep, and coping with dark thoughts. I miss her deeply and want to know what I can do to address this situation. Thank you for any advice or insights you might have.
