Sad, reading things like this but agree with others. Regret is often a post-breakup feeling. You've expended hopes and energy all to nought.

However, to presume fear of commitment is a bit dodgy. Commit to what? A lifetime with someone? A set of expectations to which they can't honestly commit? It could simply be because someone isn't ready to commit in which case it's more honestly than fear. The last thing someone wants is a pretence of commitment under some pang of emotional conscience. It happens all too often and I'd have to confess guilt of that but I learned....

If the relationship was giving you grief being unable to progress deeper then you were probably right to terminate it and there's bound to be regret. You wanted to commit. He didn't. So you had to move on pondering on what might have been.
