Idk what to do, am I overreacting?

Hi everyone , I’m a bit sad.. I had this guy come out of nowhere and hit me up on Facebook and we started to talk few months back to a year back. I was a bit skeptical because I always wondered how did he find my Facebook to even message me so I didn’t jump to talking to him so quickly plus I’ve been through a lot with my exes so I was guarded. Fast forward to times that I would catch myself liking him more and more and he does something stupid like disappearing or creating an argument and disappearing for a month or so. Then I had a car accident, & he promised to help with that since things wasn’t looking good for me after the accident. When it was time to pay he created another argument and disappeared again . He came back and we start talking again smh ( so stupid ) then things is going well . I’m falling for him again and I’m scared because I still don’t trust him ( especially on how he randomly found me to begin with) . He then AGAIN promised to do something for me and it’s something I really need. We FaceTime and I see a wedding ring on his finger. I asked about it and he said “oh I always just wear this ring theres nothing to it” Y’all wth !? He’s married !? 🥺 . I was planning to come see him for his birthday , I had so much planned and guess what ? The promise he made ? He started acting funny and slowly stop replying and is disappearing again knowing fully well I needed it. I told him if he can’t do it he should let me know and I’ll make sure to get it done . Today is the last day and he disappeared. Now I look stupid AGAIN. I’m sorry this is long but I’m tired of always being played, I always let things slide and let karma deal with people but I want to do something . The wedding ring threw me off. I’m so stupid. I want to burn a candle or something but idk which ones . Guys please help 😣 I don’t want him back , I actually want him to get hurt and played like he did me !!
