Hello Teak and Anita, thank you for your replies. Greatly appreciated that. It’s very helpful for my confusion mind at the moment.

I really want to work this relationship out, and want it to be more improvement. but until now, I’m not sure how to take it further.

Yes, Anita, you understood correctly about we were talking about my female friend did not treat me well, but he brought up my ex’s photo instead, out of nowhere, and wanted to share with me that these are examples of toxic people. he asked for my ex’s first and last name a day before, and I thought it was just casual, nothing special. He questioned me about what I’ve done, when I stopped talk to my ex, etc. I told him “I cannot remember as it happened ages ago”. but following day, he went on my ex’s social media, and saw one of his photos that I clicked on “like” and some of other photos I clicked on “love” icon, and he kept repeating that line “this guy cheated on me,” why I still talked to him few years after broke up. I seriously cannot remember the day/time/year that I stopped talking to someone, so he accused me for not telling him the truth. My ex and I decided to become friends again after few years we broke up. I forgave my ex, for what he did, but my ex is already married and we stopped talking to each other years ago.

I brought this up before with him whether if he is angry at someone toxic in his life, he refused and said no. He also shared he knows his ex blocked him, I assume here, he was looking for her profile, but didn’t see it. I wonder if he still loves his ex. For some reasons, now I end up feeling I am a back-up person in this relationship, after all the small arguments. I really feel like I’m in the middle of their unsolved case even though they’re no longer together.

Thank you for your listening and giving advice.
