Please help, I need to know if this is right.
So, I just got dumped on Friday, and I'm doing better then I thought. I've been seeing friends and all that, but I still miss her. We dated for sixteen months, and everything was fine the first seven months. Then things started going downhill, she started changing. She started wanting to leave me alone if I got upset, and she didn't want to talk or see me as much. At first I believed it to be the relationship maturing, but it got worse. At the start of the summer we stopped talking, unless it was to say goodnight or good morning. We only saw each other once a week, and eventually the times we would spend together would end up with her getting upset because she was thinking of a break. Whenever we'd text at night to say goodnight she'd say she's unsure if she loves me, or cares about me like she used too, so I said that we would talk it out in person, but her mind changed in person. The cycle repeated for a while until last week. She said she wanted a break, because she needed to figure out her feelings. I told her to go to a therapist because she is one who tends to over think a situation, and it'd be best to get an 'outsiders' perspective. She agreed to this, however, on Friday she called me and was upset. I asked why and she said she wants out. She said she couldn't take her mind changing anymore, and that it's gotten to the point where even saying goodnight frustrates her. She said she didn't care about us anymore, or to see me, or to talk to me. So I agreed to the break up. Then she said she would like to remain friends, and would tell me if she's upset and needs someone to talk too. I knew it wasn't going to happen, but I agreed. She then told me she wants her stuff back that she gave me as soon as possible(A stuffed animal that meant a lot to her was my birthday gift, but now she wants it back. As well as Christmas gifts and other things she has given to me overtime.) I'm confused as to how to give her the things back when she doesn't want to see or talk to me. I haven't talked to her since she hung up the phone, and I'm able to breathe easier than I expected. Please, if you read this far, don't judge the relationship just because we're in our final years of high school, I want it to be looked at for a relationship problem, not as a childish thing. I just need clarification on if what I'm doing is right, and how to get her stuff back to her. Or if I should even wish her Happy Birthday since her birthday's coming up. If you read this far, thank you for reading and caring.
