Would you consider this cheating?

Both in 50s.

Started casually. Hooking up, texting. I wouldn't take her out, etc.

She got feelings. I said I wasn't a relationship guy.

2 years go by of hooking up, texting. She asks again about a relationship. I said pick a few things to do. She does. But when it comes time, 8 say I'm busy.

A few months later her friend sees me on a dating site "looking for a serious relationship ".

She then goes on the site. We never talk about it. She said she was hurt. She did leave it and didn't date anyone because of feelings for me.

But I lost any feelings I had. I felt like she cheated.

Is it cheating?
