How to deal with a one-sided friendship?

I met my friend (let’s call her P) through my ex 6 years ago. We hit it off instantly and hung out when my ex and I were still together. She initially moved here where we currently are on her own as a student. I was a student as well but we went to different schools. We used to host house parties and go for day trips with my ex and some of his other friends. A year later, her husband and 5 yo moved to be with her.

The fun didn’t stop and we continued to hang out till Covid hit. I moved to a different city and she stayed back. I made an effort to text her from time to time and stay in touch. She did the same. In 2021, I broke up with my ex. We handled it well and neither of our friends were made to choose a side or anything. Inspite of this, she maintained that I deserved better and stood up for me to my ex for mistreating me throughout the relationship. I appreciated it but it wasn’t going to change anything.

I kept in touch but never with the intention to find out about my ex. She was going through a tough phase with her husband and I wanted to be there for her emotionally. I love her son and was genuinely concerned for their wellbeing.

In 2023, I started dating my current partner and she was the first friend I introduced him to. We made a day trip out of it where my partner and I visited her and we spent the whole weekend together. I went to see her again once on my own and again with my partner for her birthday.

In 2024, my partner and I decided to purchase a home together and everything worked out. It’s my first home so I was over the moon and so excited! She was the first friend I invited over. She didn’t accept or decline. She gave a generic excuse of being busy.

I decided to test her because I’d see her stories on Instagram and facebook that she’s visiting other friends in my city. I even asked her why she didn’t tell me she was visiting, and that we could have caught up. Again, she gave a generic excuse but asked me to visit her. I told her that I’m excited for her to see my house and it would make me very happy if she visited. Every time I have invited her, either the dates didn’t work out or she would ask me to visit instead.

So finally, I have just given up. She sends me reels on instagram all day but I don’t open her chat. I value conversation and she won’t have any of that with me. Since moving away, she of course, has made new friends. I’m extremely introverted and don’t have many friends.

Has anyone ever faced something similar or has any advice?

I honestly don’t want to lose this friendship.
