I've experienced both in my life. I had so many resentments and felt so alone. But eventually you have to let go of the anger, pain and resentment or it can eat you up inside. I had to accept the fact that I can't make people be the way I am or think they should be. And I can't make them accept me for who I am. If the people who have abandoned and alienated want to stay mad and keep their distance from me, there's not much I can do about that. Luckily, in my case, the fences were mended and thankfully some of the people I was estranged from are back in my life, in a limited capacity. But I am cautious about how close I get to them and keep my distance for the most part. I try to practice forgiveness, but I'll never forget how they made me feel.

Knowing that it's not your fault and accepting they are who they are and Knowing forgiveness is for you to heal and move forward, not always that they deserve it,it is for you.Maybe write them a letter and keep it for yourself to get feelings out,I find if I don't forgive I stay stuck in the hurt and I can't grow forward, so it's important to try and give forgiveness,you will be better for it.Hope this helps,and knowing some relationships can only be with set limits and boundaries to help protect yourself.

Have faith and trust wholeheartedly in the Lord 🌹😍🥰🙏😇

I needed loads of space (1500 miles) and time (2 yrs) away from Mom before I could talk to her at all. And it took even more before I got to anything approaching forgiveness. It's all been worth it though.
All very, very best to you! ❤️‍🔥
