what made you think he's committed to the 'girl-toy'? unlike serious relationships, such girls/relationships are interchangeable.
as for why he chose one girl instead of opting to be single and swinging? sorry to hurt you but isn't sex on tap better and easier than going out and looking for different girls all the time? He isn't 'committed' the way you define it, he's just having his cake and looking out for a different flavour, while keeping his old favourite (you) around just in case.
I'd have guessed that the whole point of his relationship with the girl is that it gives him what he wants (sex, companionship etc) but doesn't require real commitment from him.
May be he still loves you. That's what you want to hear. But it could just be that he likes familiarity and companionship; that's partly why people won't leave their ex's alone. I've had one friend say to her ex she doesn't understand why he needs space after she dumped him, that if he thought "logically", he'd see that they can be friends "just like before" and she should be able to call up anytime etc etc.
I don't know your ex, so this is my most cynical, hard-nosed conjecture based on what I've seen in my own life. If he loves you he will come back, in the mean time, try not to hurt yourself with theories that you can't prove.
All the best.  |
