Worried my fiancé will not be there for delivery because of AA meetings!

I don't know if there is anyone out there that can relate but please reach out if you can.  So my fiancé is almost 10 years sober but he still attends AA meetings every day and if he's not at a meeting he's meeting with a sponsee.  He gets home late every night.  I'm 34 weeks pregnant and I'm starting to worry that my fiancé would actually not be around for our son's birth.  On Fathers Day his daughter was crying because he wouldn't have dinner with her because he had to go to a meeting and meet with a sponsee after.  It broke my heart seeing him turn his daughter away like that.  He refuses to miss a meeting (although he does for work if he absolutely has to) but never for his family.  I asked him if he'd still be going to a meeting the day I give birth and when I'm in the hospital and he yelled of course!  I was like smfh.  I've been to meetings with him and it's always awkward and people just praise AA.  I don't want to resent the program, but when AA and sponsees are his most important priority I can't help but feel hurt.  He also stopped having sex with me months ago as he's very religious and wants to be a born again virgin.  I wish I could understand is this normal for someone in AA?  To still after almost 10 years sober to go to one or more meetings a day and have to put sponsees first?  I don't want him to ever relapse but is there ever a balance that can be established?  It's been suggested I go to al Anon but I don't want to because I don't have anyone to watch my kids, and I feel like people there would just attack me for resenting the program as I feel like they are the reason my fiancé doesn't want to be with me and our family.  Is anyone involved in the program or has been in a similar situation??
