Tired of waiting

It's been over 4 months since we stopped talking. We had been having ups and downs for a while and then that argument was it, all communication stopped, there was never even an official "this is over, we're breaking up" kinda thing. It just stopped. But I guess we took it as a break up.

A few weeks ago I thought I was finally starting to feel okay, I started the new semester which has helped me keep my mind off of this but I've just been missing him like crazy the past couple of days. I hate how much I've been thinking about him. Even in class my mind wanders because I'm thinking about him. I made it even worse by lurking his social media and seeing he had already resumed communication with a girl he loved before we started dating. It stings but I know he's going on with his life and I need to move on too but I fear I'm still in love with him and am not ready to have him completely out of my life.

I did some cleaning and found some of his clothes. I want to give them back and I know I will, but I don't know how or when to reach out. Some of the items have sentimental value to him and I would feel better returning them to him but I'm scared to reach out to him to ask because of how things ended. I also feel like I don't really want to give them back because I think they're an excuse for him to reach out to me, but I know I'm only hurting myself more by waiting and I need to let go. If anyone has any advice on how to go about this I would appreciate it so much.
