Search Results: i need help standing strong

So I just found out that my boyfriend likes someone else...
At first, I thought he was the one, but then realized he wasn't and tried to break it off a couple of times and yet he still tried to hold onto me over the years. As you can guess, I grew to rely on him emotionally. I used to be an independent woman, and now I've found out that he likes someone else. I don't know what to do. And I need your help please.

The things he did to me over the years that made me want to break up with him:
1) He would stop me from going to the toilet, which I found controlling (I found this odd. I broke it off last year but then decided to give him another chance hoping he'll change as he apologized and came crying).
2) He would make jokes that all nurses are dumb, or are stupid. I never found it funny but he would say "geez it was just a joke!"
3) When I had social media, and if we got into a fight, he would delete my best friends off. I covered for him and lied to my own friends that hackers got into my account. He never took responsibility.
4) We went to his ball last week and he left me to alone for 3-4 hrs while he was hanging out with his friends. I introduced myself to all of them and talked to them, yet he would just walk off and whenever I found him, he would leave me. His friends kept asking me "why does he keep leaving you? Why are you eating dinner by yourself? Oh, we'll join you!" He would act like I wasn't his girlfriend in front of them by standing far apart. When I confronted him and asked why, he said "You don't work hard enough." I told him I do because I have a strong work ethic and have plans to go to med school, but he doesn't think I can do it.
5) He says I won't get a nursing job or get into medical school

So as you can see, I feel that because I have been with him for so long, I'm used to him and his ways. While I was with him, I used to dream of leaving, now that I have a good reason to go, the thought of being alone terrifies me :/ Help?
