I sent a few messages to my ex and he has yet to respond.
Is this you attempting to get back together with him?
Umm. No way, I'm just testing him to see if he would reply.
When you break up with someone, you should give them space to process what happened in the relationship and heal. If you send messages to an ex insinuating the possibility of getting back together when you have no intention to actually do so, you are harassing and emotionally torturing that person. You should move on and stop contacting your ex.
Damn, you're right.
I'm glad you understand my point and realize that even though he's your ex, he's still a person of worth and you should be respectful of him. Plus it's time to move on and find someone new for yourself!
