Most Helpful Girl
No it's not your fault.
In all honesty being upset when you thought you would see him is pretty normal.
Yes you shouldn't have got angry and caused an argument.
But I suspect there is something else here that has made him walk away.
Leave him to think for a little while and don't contact him at all.
This will show your not needy and gives him a chance to be with his thoughts without you bombarding him.
Then send him a message, this will let him know your still there for him as a person.
Remind him of something you did together where you both felt good perhaps.
Like... I saw this the other day, thought of you and made me smile.
Just saying 'hey how are you is a bit boring'
Lighting up a good memory in his head will help him to remember how good you made him feel rather than associate you with this 'intensity'
You may be able to open the communication. Try not to bring up the breakup or all of those questions you have right away.
However if you don't want him back just go and live your life!
There are soooo many people that could be 'the one' for you. There is no 'ones' there are 1000s and 1000s :) xx
