I married a non-JW too though me not being very comitted to it all. My mum tried to convert him and he came to a few meetings and memorials, but that didn't last.
Honestly i would say RUN!!! As much you may be in love with him you will have nothing but heartache and be torn into 2.
With the decisions of birthdays christmas and all the other holidays it may be fine not for you to worry about them but what happens when you have children will you subject to them missing out on all the activites and all the other ones like giving up extra sporting games association with friends them having to go to the meetings being a subjecive partner.
There is a lot to consider don't make a light decision.
