Questions: Dating

YES, this is a serious question! 28F, I’ve been on and off dating apps for years. For the times I’ve been on them, a lot of the guys seem off, some seem ok then show their true colors, I don't know sometimes it’s just something I can’t put a finger on. Some are odd right off the bat & I unmatch but this guy seemed ok at first. Then he asks me to add him on the gaming network & when I look him up, it’s a pic of a cartoon cat with muscles & hearts. After a few days, he wanted to know why I didn’t add him & I told him the truth. I said that there’s too many oddballs on the apps & that’s why I use them very casually, I’m not in the mood to have to deal with that (didn’t sound that rude). And he pretty much said it’s from a game, it’s just a pic & not that serious, I said it’s kind of odd & not in the mood to have to figure it out, rather just not deal with it. And he stopped msging for a while on snap, then after he replies to a story every once in a while or send a video of himself & I just left him on read.
