My father is having an extramarital affair. Part of me wants to end my relationship with him for cheating on my mom, but i worry that he will be depressed as he loves me a lot. How do I deal with this situation?

I think that sometimes when we see someone we love hurt by another person that we love, our first reaction is to walk away in disgust. Most often times though, people seek someone else due to a feeling of emptiness or because they have a lack of passion for their partner. Personally, I think that your relationship with your dad (assuming it is a good relationship) is and should remain separate from his choices. He made a decision that you disagree with, and that is very understandable, but he loves you and has not abandoned you. It is ok to feel hurt, disappointed and even angry but in the long run, your parents relationship is theirs and your relationship with them as an individual is yours. You can't control another person's emotions but you can be there for them and continue loving them in spite of their imperfections. Don't cut your dad out of your life as you would be doing yourself and him a disservice.

Maybe you should try to talk with your father first, letting him know that you are aware of the affair will help you deal with your conflicting emotions toward your father. Hating him does not mean does not mean you have to cut ties with him.

It would be best to talk to your mom about it and let them sort it out, if you feel the need to end the relationship you and your dad have, it's your choice.

There are two sides to every story and although this doesn't sound like a nice thing to hear or be situated in, its always worth hearing people out and try to be understanding rather than closing yourself away from it.

Talk to your dad, and tell him to confess to your mother that he is cheating or else you'll do it yourself. Your mother does deserve to know but better it come from him. If you feel very hurt about him hurting/cheating on your mother, ultimately it is your decision if you want to remain in contact/relationship with your dad. Don't worry about him getting depressed as you need to focus on your mental health and feelings about the situation first. He's in the wrong here and there are consequences...

For situations like these, effective communication is the only thing that works. Go have a chat with him and make your displeasure or anger at him known. Tell him that his actions are troubling you and see how it works out.

Compassion is simple but it is rarely easy. Communication is similar. I would recommend you sit down with your father and have a calm and compassionate discussion about the situation. Explain how you feel it is effecting you, how you feel it will/is effecting your mother and how seeing that is effecting you. Discussing this with him, may help you understand his reasons behind his choices and may reveal what options there are for everyone to move forward and support each other. I imagine the part of you that wants to end the relationship with him is the part of you that is hurt by his actions, there will also be the part of you that loves him immensely and this will be the part that will be patient and listen and look for solutions.

My answer here depends on your age, as it's more appropriate for an older person (adult age). If your father loves you so much, could you not try to talk to him about what he's doing? At the very minimum, it may give him an outlet to talk about why he's doing this, which would in turn at least allow you to see things from his perspective. Further to that, it might give you a chance to talk some sense into him, or to at least steer him towards a less duplicitous way of living his life.

People in toxic relationships need help from friends, family, and professionals to commit to leaving. Changing is a process not a decision. People often return to a toxic relationship, just because it is familiar and comfortable. Keep in mind that you may need to seek help multiple times or for an extensive period of time, and that is okay

Please realize that you are NOT part of the relationship between your father and your mother. I understand how it must hurt you to see your parents hurt... But you must love them both no matter what, yes? Take a look within yourself, breathe, and think about how you want your life to be. Do you want to hold onto resentment? What about letting sadness overcome your happy times with your father since you know he loves you? And you must know that your mother will always love you, as well. Just be silent, reflect, and your answer should come clear to you.
