What does " I need to figure out things" really mean?

I have this guy friend that has had a crush on me since 7th grade. He's been dating this girl for 11 years...they broke up & we hung out & ended up hooking up. She found out I was there & blew up his phone. He ended up taking her back that next day. He says he's confused & he needs to figure things out. What does that mean? He said he had fun with me but its hard giving up 11 years...he said he didn't want to marry her or have kids with her. ...he's is the most perfect guy & I like him a lot...just don't want to waist my time :(
