Relationship advice

I’m 19 and have been texting a 38yr old. It’s sounds weird I know, but we’ve developed some feelings for each other. We’ve sent nudes and have sexted a little too. He’s not at all a perv because he didn’t even know I was 19 till we started sexting and I asked if that was okay for him. He was actually hesitant at first but understood that we are both adults, so it’s okay. He has an ex wife and a 4yr old son, which does make me uncomfortable sometimes. He wants to meet up, but I feel Like that’s a big step. Is this relationship wrong? Should I end it before it becomes something serious?
