I contacted him too soon.. what if it ruins it all

It’s only been a week since I started Not Contact.
I was listening to sad music and the thought of him just got to me.
All I could think of was us being there for each other and what I would do to have that again.
He’s been with a girl for two weeks now (a rebound I believe)
We aren’t friends on Facebook so I don’t know if he’s seen the message yet and is ignoring me but this is the message I sent:
“It is very difficult for me not to talk to you. I have many positive things happening in my life that I would wish to share with you.”

Did he respond? I’m guessing he didn’t. What I would do in your situation is simple but easier said than done: 1) Continue No Contact 2) Work on yourself (aka self improvement)

If it’s meant to be, it’ll be. The worst thing we can do is try to force things IMO. Talking to friends and family helps; if there’s no one around, there’s a nice site called 7Cups that has gotten me through some dark times.
