should I wait for him? should I commit to him?

I'm a Libra dog female and he's a Taurus rabbit male we met in 2007 and we been on and off since, we both have not been ready to have a relationship in the past. (Due to insecurities) but after two years he's just shows up at my door telling me he misses and ready to have a family. But I don't think he is. Confused
