Need Help..

I fee like my relationship is slowly coming to an end! I’m almost certain we are both together because we are comfortable. Basically just going through the day to day motions of life. We have been together for 7years. I have an 11yr old from a previous partner. In general our relationship looks great. I just don’t think the emotion is there anymore.

Not sure if it sounds wrong but I almost feel like I need to “switch off my feelings” before ending the relationship.

How do I do that?
