Can someone give me advice about love?

Do you think that once you fall out of love you can fall back IN love?
I’ve been with my partner for 2 years, for a year now I have not been in love but I really want to be – it’s the weirdest thing.
I try everyday but all that happens is I seem to push him further and further away, and I don’t know if I should just do him and myself a big favor and leave or if I should keep trying to fall back in love with him again, as I really want to be in love with him!

Any suggestions?
