Help me get the spark back l

Hey all….my boyfriend and I have been together for : years. We’ve lived together 2 out of those 3 years. It’s offically hit a year since we’ve had sex.

I’ve tried everything from sending some sexy texts to surprising him in some new lingerie and yet he shows no interest and will just ignore all my advances. When i mention how long it’s been I get the response of “Im just not into it anymore” Any advice on how to get the ball rolling here so we can get our sex life we used to have back?
