My girlfriend recently started acting distant. She used to be the one who would call and text me first, but suddenly she stopped replying to my messages and calls. At one point she even blocked me when I tried to talk to her.
When I asked her what was wrong, she kept saying "leave me alone" and "can we stop talking." I got emotional and asked her directly if she loves me, and she said no. That completely broke me. Later when I asked again, she said "I don't know."
After some time and with the help of a mutual friend, she said she regrets being physically involved with me. That confused me because earlier in the relationship she was happy about it, but later she asked me not to get physical again due to some personal trauma she's been dealing with. I fully respected that and agreed immediately.
Now she told me to give her a week of space and said she'll talk to me next Monday. She specifically told me not to message or call her until then.
I don't understand what changed so suddenly. I feel lost and mentally exhausted. She was a big part of my life and now everything feels empty. I'm trying to respect her space but it's really hard.
What's the best way for me to handle this situation moving forward, especially when she contacts me next week?
TL;DR: My girlfriend of 1 year suddenly became distant, said she doesn't love me, and regrets our physical relationship due to personal trauma she's working through. She's asked for a week of space before talking next Monday. I'm heartbroken and lost — how do I handle this when she reaches out?
