Ghosted after Six Months

I need some advice. I’ve been dating this older guy (Late 30s) (I’m 28F), For exactly six months now. Everything has been great! We took it slow at first because we are total polar opposite’s and I guess didn’t even think we’d be into each other but we were. Towards the last month or so we had gotten pretty close and open about our feelings toward each other. We have a lot in common, we eat the same foods, and come to find out we even grew up in the same hometown. I don’t want to sound like a dummy but I really fell for this man and he the same for me because on the day of our 6 months of dating, we both kind of went ahead and professed our true feelings to each other. Exactly 24 hours after, I started noticing that he wasn’t replying to me at all. Over the next few days I reached out just trying to see if he was okay because at this point I was getting worried. He finally responds and says “Hey I’m okay! I’m going through a lot right now, it’s complicated. Sorry Babe” I didn’t want to be a bitch so I told him “I’m sorry, I’m here if you need to talk.”… No Response. 2 days later I reach out checking on him. All he mentions is how sweet I am for checking on him and nothing else. A week goes by and I finally reach out again and he says “No I’m not mad at you. I’m going through a rough spot with relationships rn. It’s hard. I’m so sorry I hope you understand.” Tf is that suppose to even mean? I’m hurt. Should I tell him that I’m pissed or should I just take this L and walk away? I get angrier the more I see him stalking my social media but not telling me what the hell is going on.
