Don't accept indecisiveness in a relationship. Trust me, I was with a man for three years and our relationship was literally just a series of wishy-washy answers to my very fair questions (living together, shared ownership of pets, marriage, etc.). Eventually I got sick of not being on the same page and realized that men (he was in his 30s....) won't change. So take it from me:

Maybe = No

I don't know = No

I think/don't think so = No

Soon = No

Let me think about it = No
