Trying to Decipher a Man's Mind...

So here's a little topic that I would like to hear some remarks on:

I have a friend (guy) who was in a long term relationship for about a little over a year. Long story short, he wanted to marry her and had planned to raise a family with her. But about 2 months ago he called me which he hardly ever does and seemed upset.

Another LONG story short: she wanted 'space' therefore he gave it to her a bit heart broken, she then slowly started saying her phone wasn't working so she couldn't call as much or for as long, nor could she text. Mind you he paid for this phone. She then started making excuses that she had family things on the days they always seen each other since it was long distance (bout an hour).

Then one day after a week of 'space' she broke up with him. He was devastated. then one drunken night...

he looked up online her phone bill to see if what was going on and there had been calls made from 11pm until 5 am almost every night. Sh** got real. He disconnected her phone and she flipped out. 

Lying saying it is calls her mother made to her grandmother. 

He then believed it and felt bad and started blaming himself...

Another long story short: she left on vacation for about a month and he was devastated wondering what was she doing etc. if she was sad about losing him etc.

Turns out she had a man out there...and he found out...and he still wanted an 'explanation.'

He then finds out she no longer was happy and was coming home earlier than planned...he was hopeful...she then texts him demanding to know why he disconnected her phone and was flipping out on him..

He is still blaming himself and is convinced she still loves him and doesn't know what to do to make things better...

I've told him it was over and clearly she did not appreciate him. But he doesn't seem to grasp it. & everyday its the same story "I miss her....I want to be with her...how can she tell me those things...I know she loves me.." I honestly am running out of things to tell him.

So I wonder...what should I say...?

Much love & harmony,

B
