Should I Try To Get Her Back?

I’m 22 and my gf is 21 we had a very mature relationship and we both knew that we wanted to eventually get engaged and move forwards with our lives. We always talked about the future and everything was great.

At the 3.5 year mark me and my girlfriend had some ups and downs. The last 3 weeks have been the worst we said we need some time and she wanted to figure herself out. I went 3 days without takling to her, then i txtd her and called her. She didnt respond to either of them so I wrote a love letter and took it to her house. We went for a walk, she read it, and I felt like we might get back together. We both agreed to still keep things slow.

The last 2 days I found out that she was sleeping at her girlfriends house when she told me she was sleeping at home. I randomly showed up to her house to confront her about the situation and told her that honesty and trust will bring us back together but, she got mad at me and said we arent together and taking things slow so she doesnt need to tell me anything. She said she doesn’t ask me about what I do and I shouldn’t either.

I still love her and i know she cares about me, but she says she wants to give it a serious amount of time without talking and when things cool off take things slow from there. I dont want to call her and txt her again for a while to respect her decision but I feel like she will just move on and forget about what we had. She knows I want to get back together with her, but I also told her I want her to get back with me only if its her decision not that I’m persuading her into it, because ultimately it would be pointless. What do I do? How long do I wait? I want this relationship to work out. Please help.
