My girlfriend said she started losing feelings and we are working it out

I am an 18 years old men I have been in a relationship for about 2 years and 4 months now with my girlfriend who is also 18. Earlier this week, I came back from a 2 weeks vacation in Spain, and I felt so excited to see my girlfriend as we talked about going more on dates again and taking good care of the relationship. But 2 days ago she told me that she wanted to talk to me about stuff in our relationship which she isn’t comfortable with so we then met that night. She then explained to me how she recently started losing feelings for me for some reasons, one of which is that she feels trapped in the relationship (sometimes when she wants to do stuff with her friends like trying out new experiences or stuff like that, she doesn’t do it because she feels like I am going to get mad) and also because she doesn’t feel the need to have sex as of the last month. We then talked about what we should do, for her, she still loves me but not as much as she used to and she doesn’t know what is better for her: being single or our relationship. For me obviously I want to stay with her so we came to a conclusion based on the fact that we both want our relationship to still work and not abandon what we have built over the past years. We chose to take a month where we are not necessarily in couple but with the same boudaries that keeps us a couple. On the other hand, we will most likely talk less to each other and see each other less but we both agreed that she can explore herself and do everything that she wants so that she can figure out herself what she wants to in her life. Personally I am totally correct with that, I love her more than anything and I don’t think it is a bad idea to make some changes in our relationship. I was wondering if the choice we made is good? Can she truly fall back in love again? Have this happened to you guys?
