Dear [Name],

I am writing to apologize for my behavior towards you recently. I realize that I have been isolating you and that this has been hurtful to you. I understand that this must have been difficult for you and I am sorry for causing you any pain.

I want you to know that I never meant to make you feel excluded or alone. I was just trying to figure out how to navigate a difficult situation and I handled it poorly. I understand that my actions have been hurtful and I take full responsibility for them.

I can only imagine how difficult it must have been for you to feel like you were being left out. I am sorry for not being more thoughtful about how my actions would affect you. I should have taken the time to think about how you were feeling instead of just focusing on my own feelings.

I want you to know that I value your friendship and I am sorry for not showing it recently. I want to make it up to you and I am willing to do whatever it takes to make it right. I know that I cannot undo the hurt that I have caused, but I hope that you can find it in your heart to forgive me.

Dear [Name],

I am writing this letter to apologize for the unintentional isolation I have caused you. I understand that my actions have had a negative impact on our relationship and I am deeply sorry for that.

I realize that I have been distant and unresponsive to your attempts to reach out and connect. I can only imagine how hurt and confused you must have felt as a result of my behavior. I want to let you know that I never intended to hurt you or make you feel like I didn't care.

The truth is, I was dealing with some personal issues and I felt like I needed to take some time to work through them on my own. I know this was wrong of me and I should have been more open and honest with you about what was going on. I should have communicated my feelings and reached out for help and support.

I am sorry for not doing so and for making you feel like I didn't care. I care about you deeply and I want to rebuild the trust and connection we once shared. I am here for you and I am ready to start fresh.

I hope you can forgive me for my mistake and give me another chance. I promise to be more open and honest with you in the future and to make an effort to stay connected.

Again, I am sorry for the unintentional isolation I caused you. I hope you can find it in your heart to forgive me.

Sincerely,

[Your Name]
