Most Helpful Guy
I don't text, so I don't understand the weight folks have on it.
I hear all the time, "He texts me and blah blah..."
Does he ever call? or drop by in person?
If you are going back and forth it will feed his desire to keep it going. (Textually speaking, nice pun…)
If he needs space, by all means give it to him. It's not the end of the word if you don’t communicate for like two weeks.
Also easy up on worrying so much.
It doesn’t sound like you had anything beyond a casual friendship anyway. what’s the big deal? Are you having sex with him? That complicates things. If so, end all that, ignore the pheromones. A relationship should be no effort, no wishing, no struggle.
I hope you figure it out. When I’m confused I like to take a long hike in the woods and talk it out.
