<human>: Can you give me the gist of the text in a nutshell?

February 2nd, I was catching up with my little sis by text message. We were making plans to meet that weekend, as we hadn't seen each other in a while.

Toward the end, she mentioned that she'd been dating a guy she met online for six months. This was the first I'd heard of him, and she hadn't had a bf in years, so I was pretty surprised and happy for her. Wanting to relate, I mentioned that I had a romantic (but totally non-sexual) relationship with a then-coworker at my day job.

No reply.

A few weeks have passed. I've sent her a few messages over time, trying to strike the conversation back up, but no reply.

She has a history of closing herself off to everyone except her sister (20F) when she's feeling depressed, so it could just be a coincidence that she's dropped off my radar. But maybe it was something I said? Maybe she thinks I was being a little bit Subway Jared, or even making shit up out of jealousy. I don't know. We used to confide everything in each other. I thought I could share that. We've been drifting apart lately, and I guess her new bf has just replaced me entirely.

It's been weighing on my mind ever since. I was already pretty sad about breaking up with my ex (the age gap was starting to really make me feel creepy, and I couldn't lead her on anymore), so being shut out by my sister is just making it worse. I wish I could just casually clarify to her that I never poked that kid (and I totally could have).

I had a pretty depressing, introspective Valentine's Day.
