I feel trapped in this relationship

My boyfriend and I have been together for almost four years now, and I have always hoped that he would change and become a better person. He has a lot of problems and doesn’t address them because he believes we are going to be together no matter what. It’s not as if I don’t love him but I often worry about our future because there is a sense that he wants me to accept him the way he is and make adjustments on my own if I can’t manage the things he does. There is no equality, and it is only our mutual love that prevents us from ending this. I feel trapped which is strange because I know I want to marry him. What should I do?
Being in love with someone is great, as is the awareness that you want to make a lifelong commitment. At the same time, it should be tempered with a heavy dose of realism because love alone is never enough to sustain a relationship. You have genuine cause for concern, and your boyfriend’s refusal to acknowledge and act upon this should tell you everything you need to know about what your future may possibly look like. If someone isn’t willing to change after four years, it is a sign you are wilfully choosing to ignore. Also, no healthy relationship will leave you with the feeling of being trapped, irrespective of how much love you claim to both have. Speak to him about this and think carefully about how much you are willing to put in, and at what cost to yourself. If you can be honest with yourself, you may be able to make a decision based upon your life and personal well-being.

I want to break up and not go back to a toxic relationship. How do I do this?
Try writing down why you want to do this, speak to family and friends for support, and allow yourself time to get over the person you want to leave behind.
