A few years back, my dad took his own life. I cried my eyes out the days before the funeral and just felt dead during the service. I choked through my eulogy, we buried his ashes, and everyone started talking amongst themselves. Nothing crazy, nothing big, just like he would've wanted.

The whole time, I just felt off. My mind was swimming, like I was drifting through a dream.

My dad had a buddy from work who couldn't make it for some reason, but his wife showed up.
I met them both when I was small, during a summer break where my dad took me to the oil field where he and his friend worked. His wife babysitted me while my dad and him were working.

She was...whatever. Her idea of hanging out was dragging me around and shopping for purses she couldn't afford. She took me to a movie and bowling once, but that was about it.

She showed up and offered me condolences, I thanked her and wandered off to just be by myself. Like I said, I was kind of in a daze.

I come back to the big circle of people comprised of my mom, my sister, my dad's siblings and the wife, and I arrive just in time to hear the wife talking to my family about the time she looked after me, and she follows up with "But you know what my favorite part was?" and proceeds to tell them about an extremely embarrassing thing I did while she looked after me.
Everyone else gave "yeahs" and chuckles, but I actually stumbled back from shock and embarrassment. I was so pissed I heard blood in my ears. Why was she gushing to my damn family about this during my dad's funeral, of all places?

Afterwards, the crowd dispersed and she cornered me again. She wanted to swap phone numbers "so we could hang out again sometime." She's a married 40-something who lives with her husband miles away from me, a 14 year old(at the time), and she wants to do this cutesy shit. The only reason we met in the first place is because my dad knew her husband and she was the only one there my dad knew would keep me in one piece.

She kept pestering me to copy down her number into my flip phone and at this point, I just want her to leave, but I was too much of a pushover for that, so I fumbled with my phone a little before I got frustrated and told her I'd memorize it. She has the balls to give me this amused smile like she knows I'm lying and just want to get out of this. Fuck her.

We all left soon after that and pretty soon I started coming undone and venting to my mom and sister in the car.

My sister calmed me down as best she could, but I just got this knot of anger in my chest that didn't go away for a long time.

So, am I the asshole for resenting her for the way she acted? The whole chain of events has just been bugging me lately, and I'd appreciate an outside opinion.
