AITA: guy I’m dating is divorced, should I care?

AITA or are my feelings valid? The guy I’ve been seeing for a few months is divorced, he’s about the same age as me (34F & 35M), married 2 years after a long term relationship, I guess she cheated a few times. I didn’t think I cared at first but lately find myself feeling a certain way about all of the “firsts” that won’t be as special to him because he’s been through it all before. Additionally, they had some crazy elaborate wedding with hundreds of people which I find intimidating to me (her family was extremely wealthy, not to say I’m not well off, but hundreds of people is intimidating af), also because I don’t want a big wedding, but the fact that he went through this elaborate experience leaves me feeling like anything else will be inferior to that. Also, would his family take a second wedding as seriously? My dad was married before my mom and a bunch of his family and friends didn’t come to their wedding and it really upset her, so I think of that I guess too. I know I’m feeling insecure right now but I can’t help but feel really sad and torn on all of this because I genuinely feel like he’s the one, but I can’t shake this shitty feeling either. Sorry for the jumbled thoughts, just trying to process all of my feelings right now.
