my sister confessed that she resented me for years. now what?

My sister and I have been in a strange place for a few years now. Two years ago, we met for dinner and I asked if she was okay because I hadn’t heard from her. She assured me she was fine and she was just busy. I followed up via txt and let her know it hurt my feelings that we weren’t talking and I wanted to talk to her more but the energy was still off and I just kinda distanced myself.

So I reached out last year via text to ask her if everything was ok because I still felt a disconnect. She assured me that everything was ok and that she wasn’t “necessarily mad” at me but when I drove into that further she assured me everything was fine.

This year, we did dinner and a movie and she was talking about all these other relationships and how intentional she was being so I asked what about ours? Do you have intention for ours? Where do you see our relationship and what do you need from me? She got so emotional and said that she loves me so much and wants me in her life but still didn’t tell me what’s wrong.

Yesterday we went for a walk and happy hour and I thought she was going to continue the conversation further but she didn’t. So I asked again, what’s going on. What do you need from me and what are your feelings. So from there it came out that she’s resented me in the past but now she’s moved on and she doesn’t feel that way anymore. She feels I have said things to her in the past that are mean and I throw daggers. And gave an example of something cross I said and embarrassed her by. I did apologize then and there when she brought it to my attention.

I took the time to listen and understand and explained how all of this made me feel. How all the times I felt her energy shift and felt crazy for asking. I also took the time to fully apologize for everything and commend her for sharing because I know it wasn’t easy. She wants us to go to therapy to discuss it and I agree.

However, I’m hurt by this and I don’t know how to move forward from here. I’ve never been in this place before with anyone else. Part of me never wants to talk to her again. Part of me wants to fix it and move forward and repair our bond.

Has anyone experienced this? What’s your opinion?
