Whats his deal? Is he playing mind games?

So, my ex/ son's dad ( who hasn't been involved in 7 years. My son is 7.) He's slowly trying to be a dad to my son. Which I'm allowing at the moment. He told me that he still had feelings for me and loves me. He wants me to give him a 2nd chance. But I don't want a relationship. I told him this. Well, last Saturday he disappeared. No one knew where he was. He came out the next and said he was depressed and went to the creek with a friend. That he turned his phone off. Which I don't know his phone would ring at times and then there were times when you call it would go straight to voicemail. Well he didn't tell anyone where he was. He was supposed to go somewhere with his sister that day and blew her off. Rude! I know. He said he wouldn't do it again. So him and I get along for the most part. He calls and texts me through out the week. Usually texts good morning. Today... nothing. I texted 3xs last night. Figured he fell asleep. He didn't text or call me. So I called him. Cause I thought ok maybe he's depressed. He answers says oh hey. I said him what's wrong he said nothing I'm with my friend. I was like oh ok then TTYL... bye. I hung up. He called back. But I choose not to answer because my anxiety start to race my thoughts and I was probably gonna be rude. He has called again or texted. So I'm wondering what's his deal?
