So for context we have been dating for almost 4 years now. I feel that we have had a great relationship with little to no fighting. But she has trauma from her up bringing, past relationships, and even a sexual assault incident where sometimes she can get depressed and feel bad about herself. I know I can’t do anything about the past so I just try and support her and do whatever I can to make her feel better. As of a month ago she met with a new therapist that recommended to her that she moves out for some time and work on herself. I wasn’t necessarily okay with this because we have been living together for almost 3 years now and it would be a big change to our relationship. But I eventually came to the conclusion that if she needs it for herself then it’s okay. But maybe I’m being insecure or having issues with accepting the fact that she moves out on March 4th and I’ve noticed changes in how our relationship usually is. She has been distant and we haven’t really been talking as much, she has been making weird changes to her social media accounts that she wouldn’t of done in the last year, and she has been going out more with friends without me being there . When I brought this up to her she said I should stop worrying and that we will still be together and she loves me no matter what and that it’s just for her healing and changing her routine to better herself. But with all of this happening I’m left with a feeling of being put to the side and anxiousness of potentially losing my best friend. Am I just being selfish and overthinking or should I have a serious conversation about this? Because in the end I don’t want to lose her but if it comes down to her wanting to leave me I won’t pressure her into staying in a relationship.

TLDR I am worried my gf is leaving me after she met with a therapist saying she needs to be alone for some time so she can heal alone.
