Over thinking it. Just breaths
Sounds like you might have a dysfunctional relationship, which would mean that you both are dysfunctional together. Is this a relationship ba<x>sed on sex? Might be. <br />
I would suggest counseling to help your relationship now. And even if you don't get counseling now, you will have similiar problems in your next relationship. History repeats itself. Ask your bf to go to counseling with you and if he won't, go by yourself.
Change your communication habits for awhile.
If something causes stress in a relationship or even life, change it.
Then start sending him a saucy text or two, see if he replies.
so why do you think something is going on ?
