Am I doing the right thing?

I lied saying I went to work to avoid the person I’m with for various reasons the lead up to me wanting to leave him

-I tried to leave him and express to him I wasn’t happy and he made me feel bad by saying don’t throw him away like trash and he started to cry and I stayed because I felt bad

-When I’m not in the mood for anything sexual he’s insisted on me doing something for him and if I don’t he pouts

-I’ve out grown him

-He’s not understanding of my schedule with work and school

-He thinks money is going to keep me around and always insisted on doing things for me money wise that I’m not comfortable with, I want to be independent

-One day his ex called and he put it on speaker phone for me to hear and she was talking about how his penis is an anaconda and she misses him and he made say something to her to let her know I was there which was embarrassing because he saw nothing wrong with it and he chuckled a little bit

-He’s always accusing me of having someone else because I don’t put my full time for him when I’m working to pay bills for my family and is in my senior year of college

When he contacts me I’m gonna let him know it’s over and I’m hiding out at work so he can’t make me come outside. I tried doing it and I can’t talk to him because if I do then he’s try to make me feel bad and talk his way out. Am I doing the right thing right now?
