Sounds to me like going to the gym is not actually a habit you've formed yet, just something you do here and there because you think you should.
Something that helped me make a habit out of it was progress. Once I started on a routine and actually tracked was I was doing in the gym and saw my performance increasing, it motivated me to want to keep going and see how much better I could do. Eventually being consistent just becomes a habit and you feel weird if you miss a workout, like you forgot to shower or brush your teeth.
At the end of the day the only way to make it a habit is to keep doing it until not doing it causes you some kind of anxiety or guilt. However you can trick yourself into doing that is the way to go.
