1. If there was good communication in the beginning and it has now dwindled - consistently. Sort of falling off the face of the earth for a period of time.
2. Texting/emailing/phoning has become considerably less - consistently. Or the texts or emails have become very generic. eg: How was your day? Answer: fine.
3. The desire to see you has decreased considerably. You may say, "hey, let's go for lunch" and he says, "uh yeah, I'll see." or something to that effect.
4. If sex was involved, that would become less frequent OR less intimate - more of a "function"
5. No talk of the future anymore (if there originally was).
6. Disabling the online status of chat on FB.
7. If conversation is still happening, it's generally about him. No real interest in what you're doing or have to say. Maybe an obligatory, "how are you?" and not really caring what the answer is.
8. He says he needs space with no real time line or explanation as to why.
9. You see him different places and he doesn't really acknowledge you or seem excited to see you.
10. These are all just things that MAY indicate pushing away but aren't necessarily gospel.
**Get her to flat out ask him.
