How to fall out of love? Tips?

I don’t want to explain too much but basically my boyfriend and I have decided we can be together. It’s kind of sad but I knew it was coming..we live together and the other day he said he couldn’t wait months for sex because he’s used to having it all the time...it felt kind of cold but I shrugged it off I guess now I just want to know how to fall out of love so that doesn’t bother me if and when he does take that step..of course moving out but I’m in a lease so it has to wait and I won’t ruin my credit from emotions so any tips?
