We dated for a year and I sensed him checking out. He wasn't making time for me anymore or making me feel like a priority. I messaged him about it and he acted like we make the most of the time we do have together but it wasn't true and I said ethat which made him really upset. He stopped talking to me for 3 days and I asked why we were fighting. He felt that no matter what he did I am never happy (was not the case and didn;t make any sense) he then said it's not working out and that was the last I heard from him. months went by without a single peep from him. He wouldn't respond to my messages, calls or anything. I asked for my items back and he never replied. Nothing. 2 months after this I see he's hanging out with his co-worker and hear they are dating. I wasn't shocked because he talked about her a few times but at the same time never saw her as a threat. I was devastated because I think he left me to be with this girl. 2 months after that I see him on tinder and decide to swipe right. He messaged me and I was super snarky at first but he told me how he made a huge mistake and how he feels really guilty about what he did to me. He has no idea what pain he put me through. I went weeks not being able to sleep or eat and when I would sleep I would cry myself to sleep, wake up after 4 hours and not be able to go to sleep again. I was in an emotionally/physically unhealthy state. Anyway, we get to talking and start remembering the good times and that we both miss each other. It was almost like I had forgotten about all those bad things because I had missed having him be a part in my life and liked having that back. He wants to go to lunch tomorrow to talk and give my items back. How do I talk to him? I don't want to make it easy for him but I'm scared and nervous that I will give him the impression it's okay to wrong me, when it is not, I want him to realize how much of a jerk he was and possibly have him want to work on it to make things work for us again. Advice?
