Feelings for a married man?

I have been texting a married man for 2 months now. Lately we have been texting daily but have not met. He flirts with me everyday but posts pictures of his wife and kids online. He even shared a picture of his kids with me recently. I felt hurt but didn’t tell him. He still texts me and wants to meet me. He appears a little jealous when I turn to someone else with my problems instead of him. I posted a picture of a guy friend 4 days ago, and since then this married man has ghosted me. Is it the picture of another guy (weird because he posts pictures of his family) or did he find out something about me that he dislikes? Can’t help but feel a little paranoid. Help!
