Just know what is right for you and justified from your end. You cant always do what others expect you to do. But you can always communicate about your needs, wants, willingness to do your bit and how and what you can do in a relationship and what is it that you cannot. Talking and communicating clearly is the key to transparent and fruitful relationships. That ways you can let go off guilt and other emotions which arent too healthy.

You will be able to figure things out once you talk to somebody unconnected to the issue, about it. You have too many thoughts. Leading to confusion. You need to talk to a counselor to be able to think straight and make a decision. You can consult with me or any other counselor here. All the best.
