Hi Allison!
I’m sorry to hear about this experience you’re having. It’s really hard not getting closure from someone who you thought felt the same way about you as you did with them. I have had a similar experience, and it was extremely hard to get over.
But I think once you start thinking about yourself, and shift the focus from this guy over to YOU and what you can do to feel better and peace with YOURSELF, than things really start to change.
I started doing a lot of yoga and getting deeper into the practice. It really helped calm me and created a spiritual connection with myself, that was lacking due to all of my energy going straight to the failed relationship and lack of closure.
I also spent time with my family more, and just planned for my own future and became excited about all the opportunities yet to come.
You seems young, you said you were in college right? My best advice is to focus on school and yourself and your health. Try not to give this guy too much of your energy, let him have his space and the only thing you can do is focus on you.

And if you really need to express your feelings of confusion and frustration with him, than do it. You deserve to have closure, and if he isn’t going to give that to you, than he isn’t a very respectable, loving man. He just isn’t worth it. Communicate your feelings, and if he doesn’t communicate in return, than move on and do the things I mentioned above 🙂 You will be fine!

P.S. Writing in a journal REALLY helps!
