Why am i feeling confused after he texted me?

Last Saturday I was at one of my lowest points and I texted him after not speaking for months. I needed to talk to someone about my pain. He welcomed me and helped me, even though I didn't tell him anything. Today he texted me to see me and I went out. We talked and then ended up kissing. He made it clear to me that he wants to try again.I told him that I'm not well and I can't assure him of anything, and that it wouldn't be fair to him either because there wouldn't be any security. He's seeing another girl in his life but she's shutting us down. I also saw a boy in these months. We both did it to forget about the other. But now I don't know what to do. I had all this feeling for him, but when he asked me to try again, it wasn't there. I feel apathetic right now, I think I'm a little confused. In my gut, I don't feel like getting back together with him or having anything to do with him. On the other hand, he's taking a real interest in me and how I'm doing, something he hadn't done before. I don't know if I need to talk to someone and feel comforted and safe, or if I still have feelings for him that make me want him back in my life. What shall I do? He will definitely contact me and will want to keep in touch.
