If you are ready for marriage and you love him there are no rules to love. You are right about going to fast, however you have to go with what you feel.
Even though I was 27, I have a secret. I only knew my husband 2 months b4 we got married. After I married him I learned new things about him that I did not know b4.
Like finding out he did not like dogs being inside made us have arguements. However, we both love eachother enough so we compromised.
My point is, there are no rules to love.
If you want to take a break, than you should. Go with your feelings.
