It's not easy to deal with a perceived change in attitude in our partner and of course you're asking yourself if he's breaking up "without breaking up" and how long should you wait etc etc.
As long as you're "over there" trying to figure the other person out, however, you will be in prison. You can never be happy if you're occupied with guessing another's motives.
You can never say what's in another's heart. I don't care how long he's on Facebook or how seldom he returns your tecxts. You - can - not - know - another's heart.
Focus on your own spirit, do something else for a while, try to think about something nice. Don't knock him, or yourself. just focus on being happy with YOU.
Hope this lifts your spirit a little :-)

Don't let this guy determine your happiness. The only way to solve this is to tell him how you're feeling. Prepare instances in case he tries to shrug off your claims. Communicate your feelings or he will continue to treat you this way. If he feels like he hasn't changed... leave him before he dumps you.
