These are valid points, but they don’t really apply to my situation. I’m hesitant to bring this up, as I’m afraid it will open a can of worms, but…
Mutual Friend is my best friend’s mother. She’s known me since I was eight or nine years old. She was like a second mom to me when I was growing up. She knows me.
MF is a social worker, and My Interest’s and MF’s relationship began as professional-client. After that relationship ended, they stayed in touch and became good friends. She knows My Interest.
(Disclaimer: MF did not attempt to set us up until after the professional-client relationship had ended. She also does not pass along things My Interest told her in confidence. The most she tells me is general stuff - such as the fact that My Interest has only known assholes. That information comes from MF, not My Interest. Likewise, My Interest’s information that I am a “nice guy” comes from MF, not from me.)
In all the time I’ve known MF, I don’t ever recall her “playing matchmaker.” She tossed the idea around in her head for years - literally - before introducing us. It isn’t a decision she made lightly, but she made it because after knowing each of us so well, she truly thought we would be compatible. And I thought she was right - at first…
So this is one of the reasons I’ve reacted more strongly than if I’d met My Interest on a dating site or something, and why I don’t want to be too quick to dismiss her.
