I've dated a few women who I think weren't really that invested in our relationship. One girl I dated, I swear she dated me to just get back at an ex, and once he came back to her, she broke it off with me. I also dated this another girl who I was really into. We dated for a few months, and then she just broke up with me. Saw her a week later with this dude at a bar and that was it. I get a text from her the same night, apologizing for it, and saying that she really likes me, but she's just seeing what's out there for now. But, we start to text again, and it got sexual pretty fast.
I assumed she was just on a date, but a week later, I go to the same bar again and she's there with the same dude, making out and everything. I realized, she was just keeping me around in case her current relationship didn't work out. The same night, she texts me, asking what I'm up to. I didn't respond. She got a bit annoyed by that, and called me a bitch and that was it.
Has this ever happened to you? Where you're really into someone, and you think they are too, but it turns out to not be the case and they're just stringing you along as a backup boyfriend if her current one doesn't work out.
