Reaching out to a friend I had a falling out with 14 years ago

So folks I’m trying to decide something & I need some advice. Here’s a little back story: from the age of 3 to the age of 27 I had the same best friend (let’s call her Cassie) We were extremely close but also fought sometimes because we’re both very opinionated & blunt. In our 20’s we started growing apart due to liking some different things, believing in different politics, & just generally going in different directions w/ our lives. I was very strait laced & she had become a little more wild so she was constantly getting into some trouble & I was kind of falling into a mom role with her. The last couple of years of our friendship we fought more then we had fun together but we stuck it out because of the good times of all the shared history, inside jokes, & being able to tell each other anything.

Long story short we went on a girls trip to Vegas with another long time friend as a kind of special event to remind ourselves why we were friends. I thought we were gonna shop, eat good food, see a show, hang out by the pool & go dancing, they thought we were going to get as drunk as possible & find some guys for one night stands. I was still a virgin @ the time & they knew that I wanted to wait until I was in love to have sex. The trip did not go well for obvious reasons, both of them got blackout drunk & did not really remember some of things that happened the 2nd night we were there (which included paramedics being called because “Cassie” was found unresponsive on the floor outside the club we had gone dancing in & me being sexually assaulted on the dance floor in front of “Cassie” before she wandered off & passed out) I was very upset about everything & because they didn’t really remember what happened the next day they decided I was overreacting & we had a huge fight. I have not seen or spoken to either one of them since that fight.

So now we finally come to my question (thanks for hanging in there if you’re still reading) My mom & her mom kept in touch so her mom knew when I got married & when I had my daughter & my mom told me when “Cassie” got married. I’m 41 now & I think I have more perspective on the demise of our friendship, I own my piece of it, the role I took on & that I was just as judgmental of her choices as she was of mine. I saw her Dad recently & he told me that she’d just had a baby while her mom was sick in the hospital. I really want to send a get well card to her mom & a congratulations on your new baby card to her, do you think that’s ok? Or should I just mind my own business? Also if I send the congrats card should I just write something simple & impersonal inside or could I write my number & say I’d love to see pics of her, her little one & her hubby, is it okay to include a pic of my little family? My daughter is 2.5 years old, I definitely remember what a hot mess I was in the newborn days so I don’t want to put any pressure on her or cause any drama. I hated the way things ended between us & I’d like to think we’ve both grown up enough to forgive each other for past wrongs. Am I being stupid, should I just let my mom send the cards?
