How do you fight the urge that if you reach out, they might change their mind?

I \[F, 24\] was seeing someone \[M,24\] for about three months and let me tell you, EVERYTHING was going very well. It was all green flags, we were getting along really well, and we started building a connection eventually. We went on dates, talked for hours, and he took me around the city as I was new here in the country. 2 weeks prior to Christmas, I realized that his energy changed and he was responding to my messages hours later. I always thought it was because of school/work stress but I couldn’t help dwelling on the thought that he was losing interest and I was right in the end.

We finally were able to meet one day after Christmas and I was determined to have a conversation with him regarding “what we were”. However, everything was so nice again and he was not acting cold or distant at all. He even brought me chocolate as a gift for Christmas. At that moment it made me think maybe I was overthinking the situation and I got happy. When he drove me home, that’s when his whole demeanour suddenly changed. He brought up the subject before I could in the car. It felt like a very rushed conversation which only lasted 10-15 minutes and my mind was frozen the whole time. He basically told me that he likes me a lot but he is not ready for a commitment and that I deserved someone who could communicate with me better. He said he didn’t want to lead me on while he is trying to figure out what was wrong with him and said that it’d be better if we stop hanging out for now. I had no choice but to respect his decision and walk away. But OMG, that hurt and still hurts so much. It’s been a week and he is on my mind around the clock yet I didn’t reach out to him.

However, I know that he is active on Hinge and Bumble and I can’t comprehend how he moved on so easily if it’s what he is doing.

But the urge to text him to ask “Are you sure?” and “What has really happened?” is still so strong because I genuinely like him and thought our connection was something else. We were just so happy around each other. I want to cry when I think about all our inner jokes, how he kissed my forehead and nose, the places that I’ve been to for the first time with him…Everything reminds me of him and it is so painful. I know that no contact/letting go is what is suggested but I’m scared that I might lose him and the opportunity for good. He still follows me on Instagram and I can’t bring myself to unfollow him.

I’ve been doing everything I could to keep my mind busy since last week but the pain is still there and strong as the first day. I do want closure but I’m not even sure if he ever thinks about me anymore.
