He's making me insecure. Is he doing this because I'm lacking? Or is there something wrong with him?

- Guy friend drunk texted saying he loves me. I confessed back the next day. Then said he's unsure & needed to think.

- He decided we should stay friends instead. Since then he's been leading me on whilst pursuing other girls.

- My sister prank called him. He said "you might even be funnier than your sister" & tried to phone sex. He told me my sis looks like a Bollywood actress (he never complimented me before) & hinted he could go for her.

- He found out I'm pursuing another guy now. Nowadays he's flirting with me more whilst still pursuing other girls.

People tell me I'm good looking & fun to be around. Yet how he treated me is making me doubt that. :(

He's scared of being single forever. He can see its working out with my crush.

I feel like he's going for me because he didn't like me & can't imagine why others would like me. So he's seeing me as a reliable backup.
