Do you see us as long term?

I have been with my boyfriend for 10 months and I asked him if he saw us as long term. He said "yes, I think it's possible." Is this a good sign, or does it sound like there is hesitation there? Does this response mean he isn't sure, and if he was sure, he'd give a more definite answer?

Please don't be rude, I was in a bad marriage and I'm having some anxiety now that I'm dating again, despite being single for two years after my divorce.
