Bridesmaid advice

This is a bit of a long story before I actually get to my question - so I apologize. I’m getting married next year (exact date TBD, but May/June most likely) and I’ve already chosen my sister as my matron of honor and my best friend since high school as my maid of honor. Those two were no brainers - my maid of honor is really the only close friendship I’ve maintained over the years.
I want to ask my two oldest friends (from fifth-grade up through college and into the working world) to be bridesmaids. My problem/worry is that we have really grown apart the past 3 years. We would still talk on occasion, usually just through social media - on birthdays, congratulatory occasions, etc. One of them is a teacher like me so I’d reach out to her occasionally about teacher stuff and we’d text for a day or two. The two of them have remained very close and still hang out and talk to each other regularly. (I know because they always post pictures/videos on social media when they hang out and I’d always get sad because I wasn’t close with them anymore). Up until two weeks ago, I hadn’t seen them in about 2-3 years. I was just in a different place than they were. I was in a serious relationship with my now fiancé, I was working two jobs and going to school and never had weekends free (worked at a tutoring center and subbed during the week and Target closing shifts every weekend) which was when they’d invite me to hang out. I stopped being able to hang out so they stopped inviting me to hang out. I remember one of the last times we got together, I felt out of place and “boring” like I couldn’t keep up with their adventures and stories as two single ladies enjoying young post-grad life...so admittedly it wasn’t just being unable to hang out but also uninterested. Over the years, I (and my family) would still invite them to all of our family gatherings (they were pretty much considered by my family to be my sisters growing up) over the years, even to my birthday party last December, but they would never come.
A few months ago, before I got engaged, I started reflecting on my friendships and how I don’t have any close friends besides my bff (maid of honor) and my roommate. I reached out to them about why we had grown so far apart and apologized for my part in the distance. We agreed to try to see each other soon. The day I got engaged last month, they were two of the first people I shared the news with and I immediately invited them to a graduation/engagement celebration that I was planning. They both agreed to attend right away and they both showed up this past weekend to celebrate my masters graduation and my engagement.
One of them also just graduated and she invited me, albeit last minute...literally the day before...to her graduation party two weeks ago, which I attended.
Admittedly it has been a bit awkward to hang out again after not seeing each other for so many years, but I am glad that we are trying to reconnect.
I want to ask them to be my bridesmaids because growing up I always imagined that IF I ever got married, they would both be by my side.
I just didn’t count on us growing apart and then asking them after only two weeks of us reconnecting.
Does anyone have some experience or advice of what I should do in this situation?
