How can I get him more romantic?

He doesn't go out of his way anymore, probably because he doesn't feel he has to impress you anymore .

Let him know that you still like going on dates, flowers, and to be told compliments, and that you are inspired to do nice things for him when he does those kinds of things for you .

try starting to be romantic like sizzle things up.try to surprise him w something new then he ll get the idea

I totaly agree with the last two. Take the initiative and DO SOMETHING!!

Talk to him about it before you jump out of the relationship.

You could do whatever it is to help him be romantic again. Remember it does take two.
