<human>: So 3 months ago I broke up with my girlfriend and lost my best friend (her) in the process. It was the culmination of a strange, depressed, quarter life crisis part of my life. She was my best friend and we were/are so in sync on everything. But I had a phase and I didn't realize what i wanted and I ended up breaking up with her and completely crushed her heart. She doesn't open up to people ever and she opened up to me and I ended up breaking her heart into a million pieces. I felt and still feel awful and want nothing more than to make it right.

I approached her after not talking to her for 3 months and it wasn't awkward at all but she explained to me that she does not trust me at all and she doesn't know if she ever will again. I have to believe there are some feelings there otherwise she wouldn't have agreed to meet me, but I need to regain her trust and I don't know how to do that exactly. I don't want to force my way into her life, but I want her to let me back in organically. Other than breaking up with her I always treated her the right way. I never lied, I wasn't abusive, mean, or any of that. I just went through a weird period where I didn't think I was in love with her the way I should have been and because of that I felt like I needed to break up with her. I thought I was doing the right thing, and maybe I did. The fact remains that I love her and miss our friendship immensely and want a second chance. She's my partner in crime and I feel so empty without her.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Broke up with my girlfriend. Broke her heart. She doesn't trust me right now, and she isn't sure if she ever will. I miss her and I need to gain her trust again.
