Hon, you've done quite a few posts like this over September. And I'd be fairly confident that you're well on your way to driving him away.
First things first, you DO have control over your words and you CAN stop begging him for more time together. Saying that you can't help but beg is all about taking no responsibility for your actions. I'm not saying that you can easily change your thought patterns, but you have to stop nagging him right now.
There's also the consideration that this relationship is simply not meeting your needs. If you're not happy and he can't/won't change, then it's time to question the wisdom of you being a couple. However, if you choose to stay, then you must do so with the acceptance that you will need to have a life outside of him.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
