What does this mean?

[Borg69]

I have now decided that I will gradually let go. I feel like it's unnecessary to like make a letting go speech or something (lol) in front of him. I also hope that this way, I will avoid a huge heartache, and be gradually get used to it.(?)

I think I can try to change my mood here now

As long as you're both ok with it, and know what it is, there's nothing wrong with having a physical relationship. But if you're getting feelings for this guy, and expecting him to respond back accordingly, then it would probably be better to distance yourself from him for the time being. There's really no need for any dramatic, "Farewell, I'm dumping you" speeches because you're not in a relationship with him.

If you really want to throw it out there and let him know you're getting in a little over your head with feelings and need to take a step back, I don't see anything wrong with that if you're willing to make yourself that vulnerable to him. There's nothing wrong with it, but most people are too chickenshit to be that honest without trying to make it some manipulative passive aggressive head game.
