You're aware that you can be a bit clingy at times, and as everyone knows, "admitting you have a problem is the first step".

Your bf seems like a decent person. He clearly loves you for you. He said that he wouldn't be interested in you if you were "normal". Remember that next time you begin to worry about him leaving; you have evidence that he loves you, not despite your quirks, but because of them!

If you are not in therapy, you should consider it. Your therapist would help you recover from the abuse you endured, allowing you to be a healthier individual capable of forming healthier relationships. I wish you the best.
