Search Results: losing feelings

So I used to date this guy and I was madly in love with him but as I realized he’s not the person I expected him to be I started losing feelings for him. he was pretending to be someone he wasn’t. He was taking me for granted and now wants me back. We decided to stay friends but I saw that he had feelings for me and I didn’t want him to hurt so I stopped texting him. He keeps texting me after 6 months of not replying and I just want to maybe be straightforward with him but I don’t think a closure comes in use but makes things complicated. What do you think? Should I tell him that I don’t have feelings for him anymore and that I don’t want to lead him on so it’s best we go our separate ways. Or is too late to text him that’s and just ignore everything and hope not to see him again. I don’t think we can be friends because he still likes me and wants to be close to me last time I saw him on accident I realized I have no feelings for him and he tried to hug me and talk to me more but he bored me so much I wanted to leave. I don’t want to be evil but I just woke up one day and I had no romantic feelings for him. And when I saw him he gained weight, stopped going to the gym and is not groomed well. He changed. I don’t find him attractive anymore.
