Do Libra men take time committing even if they love someone?

Hi. I’m a Cancer woman and my ex was a Libra man. He recently got in contact with me after dumping me a year ago. We lived together for 5 years but sometimes it seemed like he wanted to escape and be free. When I met him he said he wanted us to live together but he took a long time making a decision. He even asked me for space so he could think and decide what to do. He finally decided to move in with me. Sometimes he seemed happy but other times it seemed like he didn’t want that lifestyle of living with a woman.

Anyway, he came back and told me I’m the woman of his life and he can’t live without me. We agreed that we were going to talk to see if we could work things out. He said he was willing to make changes and everything. Then it seemed like he was indecisive again because he was giving excuses not to meet me. We saw each other briefly but didn’t had time to discuss things. It was just a quick hello. The day after he told me he doesn’t want to go back to the past anymore. So it’s like getting dumped for the second time after he told me he couldn’t live without me 🤔😔 Why would he do this? A part of me feels like he loves me but is scared of committing. I don’t expect a marriage proposal but I want us to have a meaningful relationship. How can I know when a Libra is 100% sure of his decision? At this point I think I should set him free but I hope he doesn’t come back confusing me. It’s not fair and I was too nice to give him a second chance.
