You are clearly unhappy, uncomfortable, and overwhelmed with this entire situation. Bearing that in mind, I believe you need to firmly state how you feel, and not allow any number of "babydolls" and "sweethearts" that may come from him to sway you from what you are really feeling and from what's really happening here. You see the red flags, and you've stated them throughout your entire post. Act on that and make a clean break for your own well-being. Also, make it clear that you want no further contact from him. It's been four days. Four days. Keep repeating that in your mind.

I know it can be great to hear things like pet names and admirations from a man, especially if you haven't heard them in awhile. However, that is not a reason to stick around when you know that the situation isn't right. Based on what you've said, he's pretty overbearing. It would be a huge mistake to ignore your intuition here or to lead him to believe that there is any possibility of anything more happening.

If, after doing this, he persists in contacting you, ignore him. Don't take his calls, and don't respond to his text messages or emails. You deserve to be in a relationship that makes you happy, and not one that makes you horribly uneasy! Keep that in mind as you move forward.

Best of luck to you!
