To AQUAGIRL 18,
It seems you are madly in love with him. Unfortunately, he is not ready to commit. It's up to you if you want to have this kind of physical relationship with him.
Hope you guys have a heart to heart talk.
The disadvantages of this kind of physical relationship without commitment, if it ends it will break both of your minds, hearts, and souls. Because even if you tell yourselves that you don't have a commitment with each other but this physical relationship has been on going for months, your minds, bodies, and souls had become one from the start.
Hopefully, all things will work out between you guys. It's right to use our hearts but it is also wise to use our minds.
