Hanging in there with hope

[Tamjakr]

So he texted me and asked if he could bring me a check and pick up his sweatshirt. Mind you, the others times he would stop by things would lead into kissing , etc. So I think he may have been testing me to see what I would do. I kept my distance, we had a nice convo about nothing important. When he left I gave him a quick peck on the lips! I was so mad at myself! Of course I'm sure he didn't mind but he said " was that appropriate". I said no, sorry and maybe you shouldn't stop over for awhile. He's with OW still. I have to stay strong and see if this rebound relationship runs its course or I finally move on but deep down I still feel like he's confused or maybe not, maybe just wants to keep me strung along. Anyway, that was yesterday- back to no texting or calling today! Any advice? Jokes? Rants, etc...
